Which units are used to express frequency?

Explanation:
Frequency measures how many times something repeats in one second. The unit used for this is the hertz (Hz), where 1 Hz equals one cycle per second. In electrical practice, this is why you’ll hear about 60 Hz in the United States or 50 Hz in many other countries—the grid frequency indicates how fast the AC waveform repeats each second. Other units like volts (voltage), amperes (current), and ohms (resistance) describe different quantities, not frequency, so they aren’t used to express how often a waveform repeats.
