Watts to Amps Formula

DC Watts to Amps Calculation

I(A) = P(W) / V(V)
The I (current) in A (amps) is equal to the P (power) in W (watts), divided by the V (voltage) in V (volts).

AC single phase watts to amps calculation

I(A) = P(W) / (PF × V(V))
The phase I (current) in A (amps) is equal to the P (power) in W (watts), divided by the power factor PF times the RMS V (voltage) in V (volts).

AC three phase watts to amps calculation

I(A) = P(W) / (√3 × PF × VL-L(V) )
The phase I (current) in A (amps) is equal to the P (power) in W (watts), divided by square root of 3 times the power factor PF times the line to line RMS voltage VL-L in V (volts).

Amps

Amps measure the flow of electricity as an electric current. Specifically, it measures the amount of electrons that flow past a certain point per second.

Volts

Volts are the measurement used to determine how much force is needed to cause the electric current to flow.

Watts

Amps and volts combine to create watts, a measurement of the amount of energy being released. The higher the wattage is, the more power and output from the appliance.

AC and DC power systems

The labels ‘AC’ and ‘DC’ are used to illustrate the types of current flow in a circuit. For direct current (DC) the electric current flows only in one direction. Alternating current describes the flow of charge that changes direction periodically. As a result, the voltage level also reverses along with the current.
