An ac is given by equation I = I1 cos ωt + I2 sin ωt. The rms value of current is given by :
- \(\frac{\mathrm{I}_{1}+\mathrm{I}_{2}}{2}\)
- \(\frac{\left(\mathrm{I}_{1}+\mathrm{I}_{2}\right)^{2}}{\sqrt{2}}\)
- \(\frac{1}{\sqrt{2}} \sqrt{I_{1}^{2}+I_{2}^{2}}\)
- \(\frac{\mathrm{I}_{1}^{2}+\mathrm{I}_{2}^{2}}{2}\)
Answer
(C) 1 2 I_ 1 ^ 2 +I_ 2 ^ 2
