PhysicsEasysingle choice

An AC voltage $V = 20 \sin 200 π t$ is applied to a series LCR circuit which drives a current $I = 10 \sin (200 π t + \frac{π}{3})$ . The average power dissipated is:

Options:

Answer:

Solution:

The average power dissipated is, $< P > = I V \cos ϕ$

$= \frac{10}{\sqrt{2}} \times \frac{20}{\sqrt{2}} \times \cos 60 °$

$= 50 W$
