What is the total power used in a circuit that has ten single phase motors wired in parallel? Each motor pulls 2A at 240VAC with a frequency of 60Hz.

Explanation:
When motors run in parallel, they all see the same supply voltage and the total power is the sum of each motor’s power. Each motor draws 2 A at 240 V, so the power for one motor is P = V × I = 240 × 2 = 480 W. With ten motors, the total power is 10 × 480 W = 4800 W. The frequency (60 Hz) doesn’t change this calculation here. So the circuit uses 4800 watts.
