Homework Statement



A series RLC circuit contains the following components: R = 250 Ω, L = 0.300 H, C = 3.00 µF, and a source with ΔVmax = 240 V operating at 70.0 Hz. Our goal is to find the phase angle, the power factor, and the power input for this circuit.

(g) Find the power input to the circuit.

Homework Equations





The Attempt at a Solution



I've searched through my book but I cannot find how to calculate the input power of the circuit.
I've tried to use P=IV to find the input power, but I still cannot find the correct answer.:cry:

Only one of those elements dissipates power. Which element is that?

What is a formula that gives the power that element dissipates?
