What is the unit used to measure frequency?

• A. Hertz (Hz)
• B. Volts (V)
• C. Ampere (A)
• D. Watt (W)

Answer: (A)

Frequency is the number of times something repeats in a given time. The standard unit for this is the hertz (Hz), defined as one cycle per second. This unit is used to describe how often periodic events occur, such as the oscillations of alternating current or signals. For example, 60 Hz means the current cycles 60 times each second. The other options measure different things: volts measure electrical potential, amperes measure current, and watts measure power, none of which describe how often a repeating event happens.
