Q. In AC circuits, AC meters measure
✅ Correct Answer: (C)
rms values
Explanation: An AC meter calibrated to accurately read RMS voltage or current on a pure sine wave will not give the proper value while indicating the magnitude of anything other than a perfect sine wave. This includes triangle waves, square waves, or any kind of distorted sine wave.
