Question

    In AC circuits, AC meters measure –

    A mean values Correct Answer Incorrect Answer
    B rms values Correct Answer Incorrect Answer
    C peak values Correct Answer Incorrect Answer
    D mean square values Correct Answer Incorrect Answer

    Solution

    Voltages and currents for AC circuits are generally expressed as rms (root mean square) values. For a sine wave, the relationship between the peak and the rms average is: rms value = 0.707 peak value.
