Frequency units?

Frequency units?

• A. Amperes
• B. Volts
• C. Hz
• D. Ohms

Answer: (C)

Frequency is the rate at which something repeats per unit time, specifically how many cycles occur each second. The unit for this rate is the hertz, abbreviated Hz, meaning one cycle per second. This is the standard way we describe repeating signals like AC waveforms or radio signals. A familiar example is household AC power, which in many places runs at 60 Hz, so the waveform completes 60 cycles every second. The other options measure different electrical properties: amperes are current, volts are voltage, and ohms are resistance. So Hz is the unit that directly expresses how often a periodic signal repeats per second.
