Find the rms value of current from t=0 t...

Find the rms value of current from t=0 to t=`(2pi)/(omega)` if the current avries as `i=I_(m)sin omegat`.

Text Solution

Verified by Experts

`i_(rms) =sqrt((underset((pi)/(2omega))overset((2pi)/(omega))int I_(m)^(2) sin omegatdt)/((2pi)/(omega)))= sqrt((i_(m)^(2))/(2))=(I_(m))/(sqrt2)`
