Find the rms value of current `i=I_(m)sin omegat` from `(i) t=0 "to" t=(pi)/(omega)` (ii) `t=(pi)/(2omega) "to" t=(3pi)/(2omega)` |
|
Answer» `i_(rms) =sqrt((underset((pi)/(2omega))overset((pi)/(omega))int I_(m)^(2) sin omegatdt)/((2pi)/(omega)))= sqrt((i_(m)^(2))/(2))=(I_(m))/(sqrt2)` `(ii) i=sqrt((underset((pi)/(2omega))overset((3pi)/(2omega))int I_(m)^(2) sin omegatdt)/((pi)/(omega)))= sqrt((I_(m)^(2))/(2))=(I_(m))/(sqrt2)` |
