How to convert watts to amps

You can calculate amps from watts and volts.

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

What is the current in amps when the power consumption is 12 watts and the voltage supply is 12 volts?

12 watts / 12 volts = 1 amps

How to convert amps to watts

You can calculate watts from volts and amps.

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

What is power consumption in watts when the current is 3A and the voltage supply is 15V?

15 volts × 3 amps = 45 watts

How to convert watts to volts

You can calculate volts from watts and amps.

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

What is the voltage in volts when the power consumption is 100 watts and the current flow is 10 amps?

100 watts / 10 amps = 10 volts
