Calculate the value measured by PMMC when a sinusoidal voltage signal

1.	Calculate the value measured by PMMC when a sinusoidal voltage signal V(t)=20sin(ωt) is applied to it.(a) 1 V(b) 2 V(c) 6 V(d) 0 VThis question was posed to me in examination.This intriguing question comes from Electrical Drive Systems topic in chapter Electrical Drive Systems and Components of Electric Drives
Answer» Right answer is (d) 0 V Best EXPLANATION: PERMANENT magnet moving COIL instrument measures the AVERAGE VALUE of the input signal. The average value of the sinusoidal signal is 0 V.
