An alternating current is given by the equation \(i={i}_{1}\sin \omega t+{i}_{2}\)\(\cos \omega t\). Then rms current wi…

\(\frac{1}{\sqrt{2}}{\left({i}_{1}^{2}+{i}_{2}^{2}\right)}^{\frac{1}{2}}\)

\(\frac{1}{\sqrt{2}}{\left({i}_{1}+{i}_{2}\right)}^{2}\)

\(\frac{1}{\sqrt{2}}\left({i}_{2}+{i}_{2}\right)\)

\(\frac{1}{2}{\left({i}_{1}^{2}+{i}_{2}^{2}\right)}^{\frac{1}{2}}\)
