An alternating current is given by the equation i = i 1 sin ω t + i 2 cos ω t . The rms current…

1. $\frac{1}{\sqrt{2}}{\left(i_1+i_2\right)}^2$
2. $\frac{1}{\sqrt{2}}\left(i_1+i_2\right)$
3. $\frac{1}{2}{\left(i_1^2+i_2^2\right)}^{\frac{1}{2}}$
4. $\frac{1}{\sqrt{2}}{\left(i_1^2+i_2^2\right)}^{\frac{1}{2}}$
