[mba444]

Homework Statement

An effective AC voltage of 170 V at 60 Hz
is applied to an RLC circuit with 20.7 mH
inductor, 0.162 μF capacitor, and 55.1
resistor in series.


a) What is the effective current? Answer in
units of A.

b)What is the power factor of the circuit?

c) What is the power consumed in the circuit?
Answer in units of W.

Homework Equations

a) I(rms) = I/sqrt (2), I= emf/Z
b) power factor = R/Z

The Attempt at a Solution

im totally lost i know that those are the related equations but i have difficulties in solving .. since i don't understand this chapter well

need your help please
