Hertz is a unit that measures which of the following?

• A. Voltage
• B. Frequency
• C. Resistance
• D. Current

Answer: (B)

Hertz is a unit of measurement that specifically relates to frequency. It quantifies the number of cycles per second of a periodic phenomenon, such as sound waves or electromagnetic waves. One hertz (Hz) equals one cycle per second. This measurement is crucial in various fields, including physics and engineering, as it helps describe the behavior of oscillating systems. In contrast, voltage measures the potential difference in electrical energy, resistance quantifies how much a material opposes the flow of electric current, and current refers to the flow of electric charge. These concepts are distinct from frequency and are measured using different units: volts for voltage, ohms for resistance, and amperes for current. Understanding frequency in hertz is essential for applications involving waves, signals, and alternating current, establishing its importance in electronics and communication technologies.
