I have the equation E(t)=7*sin(11000t+∏/3) and I measured the following:(adsbygoogle = window.adsbygoogle || []).push({});

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!
