The units of frequency are __________.
- Meter
- Kilos
- Hertz
- Pascal
Hint:
- Frequency is the rate at which current changes direction per second
The correct answer is: Hertz
- Hertz is a unit of frequency (of change in state or cycle in a sound wave, alternating current, or other cyclical waveform) of one cycle per second. It replaces the earlier term of "cycle per second (cps)."
- Hertz is represented as Hz.
