The time for one complete cycle of a 60 Hz electrical supply is approximately

Explanation:
The time for one complete cycle is the period, which is the reciprocal of the frequency. For a 60 Hz supply, the period T = 1/60 seconds, which is about 0.0167 seconds (roughly 16.7 milliseconds). The other options correspond to different frequencies (0.0333 s would be about 30 Hz, 0.0083 s about 120 Hz, and 0.1 s about 10 Hz), so 0.0167 s best matches a 60 Hz signal.
