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, $< P >= I V cos ϕ$

$= \frac{10}{2} \times \frac{20}{2} \times cos 6 0^{\circ}$

$= 50 W$
