Calculate the value measured by PMMC when a sinusoidal voltage signal

1.	Calculate the value measured by PMMC when a sinusoidal voltage signal is applied to it.(a) 15 V(b) 0 V(c) 16 V(d) 18 VI had been asked this question by my college director while I was bunking the class.The origin of the question is Electric Traction Services topic in section Traction Drives of Electric Drives
Answer» Right option is (b) 0 V The best I can explain: PMMC instrument MEASURES the average of the input signal. The SINUSOIDAL voltage signal is symmetric about the origin. The average value MEASURED by PMMC is zero.
