Question

Electrical power (P) is measured in watts using the formula P = V · I where V is the voltage in volts and I is the current in amperes. If there are 40 volts running to a light bulb of 60 watts, how much current is flowing through the light bulb?

Answer 1

1.5 amps

Explanation:

P = V.I

60 = 40.I

60/40 = 40.I/40

I = 1.5
