An alternating current is given by the equation $i = i_{1} \sin ω t + i_{2} \cos ω t$ . The rms current will be:

Answer:

Solution:

$i = i_{1} \sin ω t + i_{2} \sin (ω t + 90)$

$i = \sqrt{i_{1}^{2} + i_{2}^{2}} \sin (ω t + ϕ)$

$i_{rms} = \frac{i_{0}}{\sqrt{2}} = \frac{\sqrt{i_{1}^{2} + i_{2}^{2}}}{\sqrt{2}}$
