What is equal to one cycle per second?

• A. Hertz
• B. Ampere
• C. Volt
• D. Watt

Answer: (A)

One cycle per second is called a hertz. The hertz is the SI unit for frequency and is defined as cycles per second (Hz = 1/s). It tells you how often a repeating event occurs each second—so if a wave completes one full cycle every second, its frequency is 1 Hz. The other terms refer to different electrical quantities: ampere measures current, volt measures electrical potential difference, and watt measures power, none of which describe how often something repeats over time. So the term that matches one cycle per second is hertz.
