In an AC circuit, the instantaneous values of emf and current are $e = 200 \sin 314 t$ volt and $I = \sin (314 t + \frac{π}{3})$ A $.$ The average power consumed in watt is

Options:

Answer:

Solution:

$V_{r m s} = \frac{200}{\sqrt{2}}, I_{r m s} = \frac{1}{\sqrt{2}}$

$∴ P = V_{r m s} I_{r m s} \cos ϕ = \frac{200}{\sqrt{2}} \frac{1}{\sqrt{2}} \cos \frac{π}{3} = 50 W$
