What is the standard unit used to measure cycles per second?

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

Answer: (B)

Frequency is how often something repeats in a given time, specifically how many cycles occur each second. The standard unit for this is the hertz, symbol Hz, defined as one cycle per second. This unit is used across many fields for any repeating signal, from audio waves to radio transmissions and electrical power. The other options measure different quantities: ampere for electric current, watt for power, and volt for electric potential. So the unit that directly represents cycles per second is the hertz.
