Question

An AC voltage V = 20 sin 200 π t is applied to a series LCR circuit which drives a current I = 10 sin 200 π t + π 3 . The average power dissipated is:, 21 . 6 W, 200 W, 173 . 2 W, 50 W

MARKS App · Accepted Answer

The average power dissipated is, P > = I V cos ϕ = 10 2 × 20 2 × cos 60 ° = 50 W
