How to Convert Volts to Amps

How to convert voltage in volts (V) to current in amps (A).

Volts to amps calculation formula

The current I in amps is equal to the power P in watts, divided by the voltage V in volts:

I = P / V

So

amp = watt / volt

Or

A = W/V

Example

What is the current flow of an electrical circuit that has power consumption of 45 watts and  voltage supply of 15 volts?

I = 45W / 15V = 3A
