The average value of current `i=I_(m) sin omega t from t=(pi)/(2 omega )` to `t=(3 pi)/(2 omega)` si how many times of `(I_m)`?

Explanation

`l_(rms) =sqrt((underset(0)overset(pi/omega)int I_(m)^(2)sin ^(2)omega t dt)/((pi/omega))=sqrt(I_(m)^(2)/2)=I(m)/sqrt2` , (ii)`ltigt =sqrt((underset(pi/(2omega))overset((3pi)/(2omega))int I_(m)^(2)sin ^(2)omega t dt)/(pi/omega))=sqrt(I_(m)^(2)/2)=I_(m)/sqrt2`
