Question 438Electricity & Electronics - Assistant Engineer

The correct answer is D) 0.016 of a second. In a 60 Hz AC system, the duration of one complete cycle is the inverse of the frequency, which is 1/60 of a second or 0.016 of a second. This is because in a 60 Hz system, the AC waveform completes 60 cycles per second, and the duration of each cycle is the reciprocal of the frequency, which is 1/60 of a second. The other options are incorrect because they do not accurately represent the duration of one complete cycle in a 60 Hz AC system. Option A) 60 seconds is too long, Option B) 6 seconds is too long, and Option C) 1 second is also too long.
