What is the unit of measure for frequency?

The unit of measure for frequency is Hertz. Frequency refers to the number of cycles of a periodic phenomenon that occur in one second. In electrical and electronic contexts, it often relates to the alternating current (AC) signal, where it indicates how many times the current alternates direction within one second.

One Hertz is defined as one cycle per second, making it a fundamental unit in various fields, including physics, engineering, and telecommunications. This measurement is crucial for understanding system behaviors, particularly in AC circuits, where frequency has significant implications on the performance and design of electrical devices.

The other options pertain to different physical quantities: Amperes measure electric current, Volts measure electric potential, and Watts measure power. Each of these is essential in their respective contexts but does not measure frequency.
