I have the equation E(t)=7*sin(11000t+∏/3) and I measured the following: E(.22ms) = .422V Frequency = 1.751kHz Period = 572.0 μs Peak = 7V Peak-Peak = 14V E(rms) = 4.8V E(average) = 105mV I've calculated the following to compare E(.22ms) = .422V Frequecy = 1.75 kHz Period = 571.4μs Peak = 7v Peak - Peak = 14v E(rms) = 4.95v E(average)=4.459V--------------------This value is no where near the measured value. I'm using the formula Peak*0.637. Is this wrong? I'm not really sure. please help!
