The frequency of an alternating current is____________?
Correct answer: C. the number of waves passing through a point in one second
- A. the speed with which the alternator runs
- B. the number of cycles generated in one minute
- C. the number of waves passing through a point in one second
- D. the number of electrons passing through a point in one second
Explanation
Frequency is the number of complete cycles occurring each second, measured in hertz. It is not the alternator’s rotational speed unless the number of poles is also specified.
