In operation an electric toaster has an rms current of 3.95 AA when plugged into a wall socket with rms voltage 1.20×102V1.20×102V . Find the toaster's average power.

Explanation:

Formula for calculating the average power P = IV. It is measured in watts

Given parameters

Root mean square current Irms = 3.95A

Root mean square voltage Vrms = 1.20×10²V

Required

Toaster's average power P

Using the formula above, P = Irms*Vrms

Substituting the given parameters;

P = 3.95 * 1.20×10²

P = 3.95 * 120

P = 474 Watts

Therefore the toaster's average power is 474Watts
