Watt is a measure of power. One watt (W) is the rate at which work is done when one ampere (A) of current flows through an electrical potential difference of one volt (V) .

Amps(A) short for ampere is the base unit of electric current.

**Formula to convert watts to Amps.**

To convert W to A, we use the formula below.

Volts is the the SI unit of electromotive force, which is the difference in potential that would carry one ampere of current against one ohm resistance.

**Example:**

Suppose a bulb consumes 100 watts when it is on, calculate the current in the circuit if the voltage is 120 volts.

Therefore, the current is 0.83 amps.
