Which unit is used to measure the frequency of AC signals?

Explanation:
Frequency tells you how often an alternating current waveform repeats in one second. The unit for that rate is the hertz (Hz), which equals one cycle per second. Volt, ampere, and ohm measure voltage, current, and resistance, respectively, not how fast the wave repeats. So when you’re talking about how often an AC signal cycles per second, Hz is the appropriate unit. For example, mains power in the US runs at about 60 Hz, meaning 60 cycles every second.
