How To Calculate Voltage, Wattage, And Resistance

  |   Electronics   |   5 Comments

Most people outside the engineering field don’t really understand the difference between voltage, watts, ohms, and amps. While they do encounter all of these terms in their day-to-day life, they don’t understand how they affect the performance of the electronics and electrical equipment. However, if you understand what these concepts are and how they’re connected to one another, you’ll be able to understand your electrical equipment and electronics better. Here’s a brief explanation of these concepts.

What are They?

To understand how to calculate voltage, wattage, and resistance, you need to understand what they are.

Voltage

Voltage is known as an electromotive force. It defines the potential difference in charge between two sections of an electric field. You can consider it akin to water pressure. The higher the voltage, the greater the flow of electrical current.

Watt

Watt is an SI unit and showcases the measure of power. It measures the rate at which energy is dissipated, radiated, or absorbed. That’s one of the reasons why light bulbs and other such electrical fixtures.

Electrical Resistance

As electricity moves, its power reduces and fades a little. Electrical resistance is similar to this concept. When power moves through an electrical device, the current flow slows down. So resistance is a unit that measures just how much the current flow can actually slow down. It’s usually measured in ohms. You can compare this to the flow of water through pipes. The thinner the pipe, the higher the resistance.

Current

The rate of flow of electrical current is measured in amps. Current is directly related to voltage. So, if the voltage is high, the flow of current will be high as well. This is usually featured in your energy bills as it showcases just how much power you draw from the main line.

How to Calculate Them

If you want to calculate these units, you need the values of other units. There are many different formulas out there that would help you measure each unit. We’ll discuss the simplest ones here.

Watts = Amps x Volts

One watt is one ampere of current flowing at the speed of one volt. You can also express this formula as P=VI, Power = Voltage multiplied by Current. So, the power of a 5A and 2V bulb will be 5×2 = 10. That particular bulb will emit 10W of light.

Voltage = Watts/Amps

If you’re even vaguely familiar with mathematics, you must have deduced a way to calculate both voltage and amps based on the first formula. You just need to switch positions. The first formula was W=AxV, the second is V=A/W. Given the example above, we can calculate V=10/5. The result is 2V.

Amps = Watts/Volts

By now, you might’ve figured it out. The formula for calculating amps is A=W/V. If W is 10 and V is 2, then A is 10/2, which equals to 5A.

Ohms = Volts/Amps

As we mentioned before, ohms is the measure of resistance. According to the Ohm’s Law, R (Resistance) = Volts/Amps. So, if the voltage is 2 and the A is 5 then the resistance is 5/2, which equals 2.5 ohms.

There are different ways to calculate voltage, wattage, and resistance. If you want to carry out more complex calculations with more values, you can explore those formulas.

    Some people, especially those running on busy daily schedules tend to use the pills to help maintain weight since they can not afford to follow all the diet programs. This is not advised. It is recommended that one seek advice from a professional in this field before using the pills. This can save one from many dangers associated with the misuse.

    The diet pills should always be taken whole. Some people tend to divide the pills to serve a longer period of time. This is not advised and can lead to ineffectiveness. If it is required that one takes a complete tablet, it means that a certain amount of the ingredients are required to achieve the desired goal. It is also recommended that one does not crush the pill and dissolve it in beverages. Chemicals found in beverages have the potential of neutralizing the desired nutrients in the pill thereby leading to ineffectiveness. The best way to take the tablets is swallowing them whole with a glass of water.

    The diet pills speed up the metabolic processes. This is the key factor that leads to the burning of all the fats in the body. This means that one passes out lots of urine, which subsequently leads to dehydration. It is imperative that the user take lots of water round the clock. This will help curb dehydration, which can lead to health problems. In addition to that, water offers the required medium for the function of the nutrients and elimination of the fats.

    When buying the review of diet pills, it is imperative that one gets the most recommended dose. People tend to compromise the quality and effectiveness of the tablets due to the variation in cost. The low priced pills depict poor quality, which means their effectiveness is not reliable. Some have also been found to cause health problems. The dose should also be taken as recommended. Over dose will not speed up the process but rather lead to complication. This will increase risk of side effects. If the taking of the pill is forgotten, do not take more to compensate for the lost time.

    The diet plan enclosed with the diet pills has also to be followed. According to the requirements, the termination of the diet must be done even with no results. This means your body is irresponsive.

    You actually make it seem really easy together with your presentation however
    I in finding this matter to be actually something which I think I’d never understand.

    It sort of feels too complicated and extremely vast for me.
    I am having a look ahead for your next post, I’ll attempt to get the hold of it!

    Trying To Find The Best Diet Pill?

    Trying to find the best diet pill may seem like an impossible task, especially with the multitude of diet pills available for purchase. Many people purchase a diet pill only to find out that the pill makes them feel jittery, nervous, or often has no effect at all.

    Diet pills frequently contain the same or similar combination of ingredients and rarely contain anything new, innovative, or undiscovered to the supplement / weight loss industry. So, how can you find the best diet pill when most diet pills are made with similar ingredients?

    One of the most common problems associated with taking diet pills is that the person taking the diet pill is uneducated about the dosage, effects, and promises offered as they relate to each diet pill. The research at website finds that there are three factors that should be taken into consideration when deciding to take a diet pill.

    Dosage:
    It is important to take the pill exactly as recommended on the product label. Some people choose to increase the dosage thinking that the product will work faster or better. This is not the case, and many people become sick in response to the large dose. Reviewers at website often suggest that the recommended dosage be cut in half to give the body time to adjust to the stimulant in the diet pill. After the body has adjusted, it is fine to begin taking the regular dosage as recommended on the product label.

    Effects:
    The effects listed on the product label are there because these are the effects that the product has had on ‘some’ of the test group. Some of the diet pill testers may be fine taking the product, while others may have adverse effects. The diet pill companies print this information to educate the buyer as well as to protect themselves from lawsuits. The consumer needs to read the label and educate themselves before taking the product. Many people who are sensitive to caffeine are surprised when the diet pill makes them feel nervous or nauseous, but this information is likely printed on the product, so with a little research these affects can be avoided.

    Promises:
    If you read the fine print on product claims for diet pills and other weight loss supplements, you will see ‘results not typical’ printed very small somewhere where you are not expected to look. The diet pills advertised on television are responsible for some of the most outlandish claims. The results claimed in these advertisements are often unattainable within the given amount of time outlined in the ad. Don’t expect to see results in two weeks like a lot of ads claim.

    Wouldn’t it be great if you could read reviews for diet pills from actual users of each diet pill? Diet Pill Reviews website has taken the trouble out of searching for the best diet pill. You can read reviews of over 150 of the most popular diet pills available.
