What is the unit of frequency?

The unit of frequency is Hertz (Hz), which is defined as the number of cycles per second of a periodic wave or oscillation. In other words, when we say a signal has a frequency of 1 Hz, it means that one complete cycle of that signal occurs in one second. This measurement is critical in various fields such as electronics, telecommunications, and sound, where understanding the frequency of waves or signals can influence device performance and functionality.

The other units mentioned—volts, amps, and ohms—are related to different electrical properties. Volts measure electrical potential or voltage, amps measure the flow of electric current (current), and ohms represent resistance in an electrical circuit. These measurements do not relate to frequency and therefore are not correct for this question.
