## How do Amps, Volts, and Watts work?

### Amps:

Amps are a unit of measurement for electric current flow.

### Volts:

Volts are the unit used to determine the amount of force required to generate an electric current.

### Watts:

Amperes multiplied by Volts equals Watts, the unit of measurement used to determine energy. The greater the wattage, the greater the output and power of the appliance.

## How to convert watts to amps?

To convert electrical power to electrical current (Watts to Amps), the following equation must be used:

BASIC FORMULA: I = P / V

## DC Watts to Amps Calculation:

Current in amps (A) equals power in watts (W) divided by voltage in volts (V):

I = P / V

## AC (Single Phase) Watts to Amps Calculation:

The phase current I in amps (A) equals the power P in watts (W), divided by the power factor PF multiplied by the RMS voltage V in volts:

I = P / (PF Ã— V)

## AC (Three Phase) Watts to Amps Calculation:

#### Calculation using voltage from line to line:

The phase current I in amps (A) equals the power P in watts (W) divided by the square root of three times the power factor PF multiplied by the line-to-line RMS voltage VL-L in volts:

I = P / (âˆš3 Ã— PF Ã— VL-L)

#### Calculation using voltage from line to neutral:

The phase current I in amps (A) equals the power P in watts (W) divided by three times the power factor PF multiplied by the line-to-neutral RMS voltage VL-N in volts:

I = P / (3 Ã— PF Ã— VL-N)
