To determine how fast an alternating current with a frequency of 60 hertz (Hz) changes, let's understand the concept of frequency.
Frequency, measured in hertz (Hz), represents the number of cycles per second. One hertz is equivalent to one cycle per second. Therefore, a frequency of 60 hertz means that the alternating current completes 60 cycles every second.
Given this information:
- 60 hertz means there are 60 cycles in one second.
Thus, the alternating current changes 60 times per second.
The correct answer is:
C. 60 times a second
