Multimeters are devices used to measure voltage, current, and resistance. They can be used for a variety of purposes, such as troubleshooting electrical systems or measuring the electrical performance of components.

Multimeters typically have several features, including the ability to measure AC and DC voltage, AC and DC, and resistance. Some multimeters also include capacitance and frequency measurement capabilities. Additionally, multimeters often come with various safety features, such as over-current protection and insulation testing. 

An electrician uses several different tools to do his job. A common tool that he will use is a multimeter, which tests the amount of an electrical charge in a circuit or device. The two most important things to look for in a multimeter are accuracy and durability. This article will help you find the best multimeter for your needs by listing out some helpful tips on how to choose one.

There are three different types of multimeters: analog, digital, and programmable. 

1. Analog Multimeters 

It read with pointer movement rather than numbers, so they can be more difficult to read than digital meters; however, they’re usually cheaper than programmable meters.  

2. Digital Multimeters

Digital multimeters are easier to read, but they’re more expensive than analog ones. They also require a battery to run, unlike analog meters which can be continuously used with an AC adapter or by using a car battery.

3. Programmable  Multimeters

Programmable multimeters measure voltages and calculate their root mean square (RMS) values, frequencies, true power, apparent power, and energy of the electrical signals they’re given–the one you choose mustn’t limit your measurements in any way.

A programmable meter will give you more accurate readings for use in a home or office situation where appliances cause interference on household wiring; it won’t work as well in industrial settings where machinery is all the time (and would cause interference).

There are a few more differences between different types, but these three will give you at least two of the most important things to look for in a multimeter. Analog meters are usually cheaper and digital ones easier on batteries, but programmable meters can measure values other than voltage and current.

Multimeters typically have a 25-250 V DC range on their analog dials, which is useful when testing circuit breakers and outlets for power. They may also have an AC or alternating current range that goes from 2 mV to 2000 V.

The higher ranges require safety precautions such as using insulated probes with ground wires if you’re testing devices with them–you don’t want to get shocked! Multimeters typically come with several standard attachments such as a spring probe and pointed probes.

There are two more factors to consider, and they both have to do with use: what you’ll measure and how often you’ll use the meter.

If you’re just doing light work around your home–like checking for blown fuses or replacing switches–a cheaper analog meter will probably serve you well; if you’re wiring homes on a day-to-day basis, however, it’s worth spending the extra money to get a digital multimeter that can handle industrial settings where appliances generate large amounts of power.

Switches and outlets tend not to cause problems in most cases, though older ones can sometimes give false readings due to their age; overall, these aren’t huge differences and shouldn’t affect your choice too much.

It’s also worth considering how often you’ll be using your multimeter–if you’re doing it every day, the extra durability of a digital one is definitely worth the cost; if it’ll be sitting in a drawer for months at a time, an analog meter will do just fine.

All three types are relatively durable and breakage isn’t common even on cheap models, but if you want something lighter or more sturdy than the usual plastic exterior, look for rubberized cases or aluminium ones with stainless steel components. You can also buy covers to protect probes from damage if they tend to snag on things as they’re plugged in and out of sockets frequently.

Eyebrows are very important, not only because they help to define your face, but also because if you lack them, the facial structure is completely different.

But what happens when you have little or no eyebrow hairs? Eyebrow tattoos are a great option that will give you beautiful eyebrows in an instant.

However, many women get disappointed after their first eyebrow tattoo experience because the result wasn’t exactly what they had expected…

If you want to have a good understanding of the process, and what you’ll be getting when you get your brows tattooed, check out these before and after photos.

The process is popular because while many women naturally have nice eyebrows, others lose their eyebrows due to stress or over-plucking. The eyebrow tattooing process involves placing pigment into the skin exactly where the eyebrow should be to restore fullness. Some people choose to get their eyebrows done to create fuller eyebrows that are completely shaped after years of overplucking.

In this post, I’m going to guide you step by step through everything involved in having your eyebrows tattoed and how much it costs.

 First: A Consultation

When you first contact a tattoo artist about getting your eyebrows done, they will likely want to meet with you for a consultation. The purpose of the consultation is to figure out exactly what kind of results you’re looking for, and how much the entire process is going to cost.

Eyebrow tattoos are permanent, so if you change your mind about the shape or colour down the road, there’s nothing that can be done about it.

Therefore it’s important to choose an eyebrow tattoo artist wisely because once they draw on your brows, there isn’t any turning back! Once you’ve chosen which artist you’d like to go with based on their portfolio and customer reviews, then I recommend setting up a time for them to take some pictures of your current brows to create a reference point.

Drawing on your eyebrows  

A drawing of how the artist envisions your future eyebrows will be created, and then they’ll ask you if this is exactly what you want too. At this stage, you need to be honest with them about what your expectations are because they are artists, not magicians. For example, I had my eyebrow tattooed once before by someone who didn’t understand my expectations.

Now I have an eyebrow that is way thicker than what I wanted, but since it’s coloured in I can make do with it!

Second: Preparing Your Skin Before The Tattoo

Owning up to your mistakes    

When the tattoo process has been completed, you’ll have to own up to your mistakes and tell the artist what you don’t like about it. This is a crucial step in the process because if you leave that for another visit, then I can almost guarantee that it’s going to be worse.

I don’t think women realize just how easy it is to overpluck brows! The good news is that tattoo artists are usually able to correct any mistakes from previous work done by other tattooers.

Third: Getting The Actual Tattoo!

At this point, the colour matching begins! Here’s where all those pictures come into play as well as a close examination of your skin tone. Usually, one session will do the trick, but some people may need two or three visits.

Since eyebrows are the “frames” of your face, I highly recommend doing some research on what colours will match you best before choosing a geographically convenient artist. Once the tattoo process has been completed, I promise your eyes will never look the same again!         

A bridal shower is a great opportunity for friends and family to come together, have fun, eat cupcakes, play games and share gifts. But you don’t want the bride-to-be stressed out about doing all of these things with her friends! It’s your responsibility to be mindful of who you invite to this event. So, who do you invite to a bridal shower?

Your guest list can make or break your party—after all, if you are known as the “hostess with the mostest” then everyone will always ask you to host their parties! Try not to stress yourself out by thinking through what type of guests will help make your bridal shower stand out from others.

Here are some simple guidelines on who should be invited to a bridal shower:

1.  The bride’s friends. 

This is the guest list that you will probably end up with regardless of your wishes because you are usually close to them yourself. However, if some people on this list tend to bring negative energy, they might not be the best choice for party guests.

If you want to have a friend come but she tends to complain about everything and leads the group in negative talk, perhaps it’s better to ask someone else or opt-out altogether so you don’t get stuck wondering why all of her friends always complain when one of their gets married!

It can add too much stress at such an exciting time in your life—especially since you are probably already stressed out about all of the wedding preparations.

2.  The groom’s friends. 

This usually doesn’t happen, but if the bridal shower is held after the engagement or after a proposal, then it would be appropriate to include males in this part of the celebration.

If you do have male guests at your party, they should not be invited unless they are close enough to qualify as being practically family—you don’t want an awkward situation where girlfriends get jealous or upset that there are men around!

Invite caution when mixing genders, especially when alcohol will be served at the party—things can get out of hand fast without realizing it until it is too late.

3.  Family members. 

This is a no-brainer. However, take care when inviting family members to your bridal shower. If you have a large family and everyone gets along well it shouldn’t be an issue, but if some people in your family don’t get along or have had fights with the bride before it might be a good idea to leave them off of the list—you can send them a separate invitation for another party.

4.  Coworkers. 

If the bride works, then she will probably appreciate having her co-workers celebrated too! It can be nice to have someone from work throw her this celebration since it may not always happen that way. However, if you want to opt out of certain coworkers at work, it can be a good idea to keep those that are closer and won’t cause any issues at the party.

5.  New bridesmaids. 

If they were recently invited to become bridesmaids, then this is an occasion where they should attend! Asking someone to be a part of this part of your wedding journey is very special and important—so make sure that you include them in all of your celebrations.

6.  Out-of-town guests. 

Being from out of town doesn’t automatically mean that you shouldn’t be invited to a shower, but if there are too many people from out of town attending, then it could make things a bit more complicated for the hostess. If you want to invite people from out of town and this is the bride’s second shower, then there should be a separate reception for guests who aren’t in town for this particular celebration.

7. Guests’ relatives. 

If you decide to add other people to your bridal shower, make sure that these other guests know not to ask their family members (i.e., mother-in-law, sister) to come along because it might become too complicated! You can split up the list into two different confirmations or send separate invitations; whatever works best for you and your guest list!

8.  Close family friends. 

These are usually grandparents and perhaps godparents—and they don’t always need to be invited to a bridal shower. However, if the bride has been very close with these family friends, then it would be nice to invite them since they will probably feel left out otherwise!

9.  Coworkers’ significant others. 

If the groom is inviting his co-workers and their spouses or significant others, it can become a double celebration for both parties involved—especially since there aren’t many reasons in this day and age to celebrate at work anymore! Inviting coworkers is always more fun when they bring their loved ones along.

Just remember that there should be different guests on each invitation so you can keep track of who all came!

10. Hostesses’ friends. 

The hostesses might want some of their friends invited to the bridal shower as well! If this is happening, then just make sure that everyone involved knows how many people are coming and keep track of who’s coming and who isn’t—it could get confusing otherwise.

11. Out-of-town guests’ relatives. 

Just like the bride’s family members, if there are too many people from out of town attending, it can become complicated for the hostesses. Some families may appreciate separate celebrations so they don’t feel left out because you should focus on celebrating with your closest family when they are in town.

You can split up the list into two different confirmations or send separate invitations; whatever works best for you and your guest list!

12. Workplace family members. 

Sometimes, co-workers invite their family members to celebrate the bride at a bridal shower! While it is nice that they want to have them involved, if everyone comes along then it can become very complicated. Instead of inviting the whole office, just pick one or two close co-workers to bring along.

13. Close relatives. 

This would be their grandparents and perhaps godparents who are often invited—and doesn’t always need to be invited to a bridal shower. However, if the bride has been very close with these family friends, then it would be nice to invite them since they will probably feel left out otherwise!


Did you know that your heart can repair itself? Of course, this is not as good as a healthy heart without problems. But what if I told you that there are ways to improve the state of your ‘bad’ heart? Can your heart repair itself?

There are things called stem cells. These cells have been found in all sorts of places throughout the body. Blood vessels and muscle tissue especially contain these small cells with incredible potential for growth and stabilization. Sometimes, even a small amount of stem cell activity can be enough to cure a disease or ailment. In the case of myocardial infarction (MI), or a heart attack, damaged tissues become an issue.

If left untreated over time, the damage leads to scarring through fibrosis. This fibrous tissue is the body’s way of patching up holes and wounds, but it can prevent blood flow from going through that section of the heart.

What would happen if we could introduce stem cells into a person’s bloodstream? Would they be able to find their way through all those thick layers of scar tissue and establish a passage for vital blood to pass by once again?

The human heart has two main coronary arteries (one on each side) that supply blood to the organ itself. When these become blocked or narrowed due to arteriosclerosis (the build-up of fatty plaques), MI occurs within minutes because there is insufficient circulation throughout the muscle to keep it nourished with oxygenated blood.

If there was some sort of process that could introduce stem cells to the site of the cardiac damage, might these little guys be able to find their way and provide arterial and ventricular support? (A ventricle is one of the four chambers in the heart.)

A team of researchers from Harvard University and Boston Children’s Hospital conducted a study on mice with MI or ‘heart attacks.’ They injected them with MSCs (multipotent stromal cells) that were tagged with bromodeoxyuridine/GFP. This treatment restored skeletal structure by increasing blood vessel formation. In short, there was less scarring present after this process was completed.

Scientists have been studying these types of stem cells for decades. The discovery of them being present in many different tissues, but not being able to differentiate into many different types of mature cells until much later on in the animal’s life has been a well-known fact. It is now postulated that these stem cells are multipotent, which means they can produce several different cell types.

The reason why this particular study is so relevant is that it hints at how future transplantations may be conducted to help treat cardiovascular disease and other degenerative conditions; even Alzheimer’s Disease (AD). MSCs can be found in bone marrow samples taken from healthy adult volunteers participating in their donor program. This is great news for anyone who may need stem cell therapy one day.

After an MI or heart attack occurs, scar tissue builds up and blocks blood flow between heart chambers, which can lead to complications between the lower chambers of the heart. Stem cells may provide a way around this problem, but through what mechanism?

Bromodeoxyuridine (BrdU) makes up part of what is known as nucleoside analogues. These are compounds that mimic the nucleic acids found in DNA during cell division. If you introduce BrdU into your system, it creates molecules very similar to deoxyribonucleic acid (DNA), except they do not contain any phosphate groups linked with ribose sugars.

This means that they cannot be integrated into normal strands of cellular DNA like their correct counterparts; thus, they remain separate throughout the replication phase until later on when they are broken down by enzymes.

In this particular case, GFP (green fluorescent protein) was also tagged to the stem cells as a method of tracking their activity. This allowed scientists to visualize what was going on with them under a fluorescence microscope. They found that the tagged MSCs were able to successfully integrate into several tissues around the heart and restore vascularity where it had been diminished due to MI.

Researchers hope that these findings will help other studies continue testing different techniques for cell transplantation therapies in animals and humans alike.
