In the United States, AC cycles per second are how many times?

Explanation:
AC frequency is how many times the current reverses direction in one second. In the United States, the standard is 60 hertz, so the current completes 60 full cycles every second. This frequency is the baseline for the design of household wiring, motors, transformers, and most electrical equipment used here. Other parts of the world use 50 hertz, which means 50 cycles per second. The numbers 120 and 180 aren’t used as standard mains frequencies in the US. (120 Hz can appear as a ripple frequency in rectified DC, but not as the mains supply frequency.)
