Question

Quizplus · Accepted Answer

The coil of a generator produces one complete cycle of alternating current (AC) with each rotation. Since it rotates 50 times every second, it completes 50 cycles per second. Each cycle of AC includes two reversals of current direction (once when the current goes from positive to negative and once when it goes from negative to positive), resulting in 100 reversals of current direction every second.
