Question

When plugged into a 120 volt wall outlet, how much current is used by a toaster rated at 1200W?

Answer 1

1200 W = 1200 Joules / sec (power = work / time)

P (power) = I V = coulombs / sec * joules / coulomb = joules /sec

I = P / V = 1200 joules/sec / 120 joules/coulomb

I = 10 coulombs / sec = 10 amps
