An alternating current is given by the equation i=i_{1} \sin \omega t+i_{2} \cos \omega t. The rms current will be [26 Feb 2021 Shift 1]

Correct Answer is : 1√2(i12+i22)1∕2

\frac{1}\sqrt{2}(i_{1}^{2}+i_{2}^{2})^{1 \/ 2}

\frac{1}\sqrt{2}(i_{1}+i_{2})^{2}

\frac{1}{2}(i_{1}^{2}+i_{2}^{2})^{1 \/ 2}
