# How to Calculate Amps For Led Lights? | Calculating Amps for LED Lights

Although there are three ways to find out the amps of your lights, the easiest one is to use the basic formula of dividing power in watts (W) by the volts (V) of voltage. For example, if the wattage of the lighting fixture you’re working with is 60 and the volts are 12, divide 60 by 12 to get 5 amps.

The amperage is also important for folks who need to choose the right size circuit for their home. You can convert the amp rating of a circuit breaker to watts, but it is easier to use amps because the rating printed on a circuit breaker is presented in amps.

## Procedure for Calculating Amps for LED Lights

A regular bedroom LED light of 10W draws just 0.083 Amps. Because LED lights consume less energy than incandescent bulbs while producing the same amount of light. But if you want to test how many amps are drawn by your LED, then you can use one of these three ways.

### Converting Watts to Amps

You can convert watts into amps by using the power formula. The power formula, which states that I = P/E, where P is power measured in watts, I is currently measured in amps, and E is the voltage measured in volts, can be used to convert watts to amps.

In this formula, take the wattage reading of your LED light and divide it by the voltage of your home. Thus, current I in amps equals power P in watts divided by voltage V in volts.

### Measuring DC Amperage with An Ammeter

You have to connect an ammeter in “series” with the LED, not in parallel. In other words, you’d have to insert it between the potentiometer and the LED and act as a “wire” connecting the two. You can also use a multimeter for this operation.

Multimeters will be rated for a specific quantity of current. If you use a multimeter rated for 10 amps and then run 200 amps through it, the fuse will blow. So, you have to be careful about the ratings.

### Calculating Amperage with Ohm’s Law

According to Ohm’s law, the current flowing through a resistive conductor (the LED) between two places is proportional to the voltage across the two points. In other words, the current I in amps (A) of a resistor is equal to the voltage VR=V in volts (V) divided by the resistance R in ohms (O) {I=V/R}. So, mainly to calculate amps, you’ll use Ohm’s Law:

**Amps (A) = Watts (W) / Volts (V)**

Let’s say you have an LED light with a wattage of 10 watts and you live in a country with a 120V electrical system.

- Amps = 10 watts / 120 volts = 0.083 amps

So, you have to take the voltage of your home and divide it by the resistance of your LED light. The value you will get here will be the amps drawn by the LED light of your home. Watts/Volts/Amps/Ohms Calculator (rapidtables.com) – this site can help you with Ohm’s law calculations.

## The Necessity of Electrical Ratings

Connecting your foodservice equipment to the incorrect voltage is the most common cause of equipment failure. If you connect your new equipment to the incorrect power supply, it will not function properly and may even be damaged.

Given the cost of outfitting your kitchen with professional equipment, you’ll want to ensure that the electrical standards are satisfied. To avoid this common error, use our voltage calculator to precisely compute amps, voltage, or watts.

## Amps

Amperes, often known as amps, are units of measurement for the flow of electricity as an electric current. They specifically monitor the number of electrons that travel past a specific spot every second. A garden hose is a typical illustration used to demonstrate how amps function.

The volume of water flowing through the hose can be compared to amps. The stronger the current, the more liters of water that flow through the hose every minute. Alternatively, as the number of electrons passing through a certain place per second grows, so do the amps.

## LED Lights Turn-on Voltage

An LED’s polarization is typically between 1.8 and 3.3 volts. Depending on the hue of the LED lamp, it varies. A red LED normally loses 1.8 volts, but when the bandgap rises, the voltage drop and frequency of light increases, and a blue LED can drop from 3 to 3.3 volts.

## Frequently Asked Questions

**How do you calculate amps to watts?**

The power formula, which states that P=I*E, where P is power measured in watts, I is the current measured in amps, and E is the voltage measured in volts, can be used to convert amps to watts. As a result, power P in watts equals current I in amps multiplied by voltage V in volts.

## Conclusion

When measuring the amps of an LED light, you should keep in mind that a usual home in America utilizes 120V. On the other hand, many European countries prefer 220-250V power supplies.
