Frequency is measured in which unit?

• A. Watts
• B. Volts
• C. Hertz (Hz)
• D. Ohms

Answer: (C)

Frequency measures how often a repeating event occurs in a unit of time. The unit of measurement for frequency is Hertz (Hz), which is defined as one cycle per second. For example, if an alternating current (AC) signal completes one full cycle in one second, it is said to have a frequency of 1 Hz. Understanding the context of frequency is crucial in electrical engineering and electronics. Frequencies are foundational in AC circuits, radio transmissions, and signal processing, where they determine behavior and interaction of components based on how quickly they operate or respond. The other options reflect different electrical concepts. Watts measure power, which is the rate of energy transfer. Volts measure electrical potential difference or voltage. Ohms measure resistance in a circuit. Each of these units plays a crucial role in electrical equations and applications, but they do not pertain to the measurement of frequency.
