If an alternating current is given by i = a sin (`omega`t) + b cos (`omega`t), then RMS value of current is :-

An altemating current is given by 1 = 1_(1) cos omega t + 1_(2) sin omega t. The RMS value of current is given by

Current in an ac circuit is given by I= 3 sin omega t + 4 cos omega t, then

Current in an ac circuit is given by I= 3 sin omega t + 4 cos omega t, then

An alternating current is given by 1 = 1 1 cos ω t + 1 2 sin ω t . sinomega t .The value of rms current is

If instantaneous current is given by i=4 cos(omega t + varphi) amperes, then the r.m.s. value of current is
