What is the unit of measurement for frequency?

• A. Watts
• B. Ohms
• C. Volts
• D. Hertz

Answer: (D)

The unit of measurement for frequency is Hertz. Frequency refers to the number of cycles of a periodic wave that occur in one second. Therefore, one Hertz is defined as one cycle per second. This measurement is fundamental in the study of electrical systems, particularly in understanding alternating current (AC) systems, where the frequency will dictate how electrical devices operate. In contrast, the other options represent different concepts within the electrical field. Watts measure power, which is the rate at which energy is transferred or converted. Ohms measure resistance, indicating how much a component opposes the flow of electric current. Volts measure electrical potential, the force that pushes the electric current through a circuit. Each of these measurements plays a vital role in electrical engineering, but they do not represent frequency.
