## Homework Statement

A series RLC circuit is connected to a 60 Hz AC source which produces an amplitude of εmax=20 V. The circuit element values are R= 20 Ω, L= 20 mH, C= 150 μF.

Calculate the total impedance of the circuit.

## Homework Equations

Xc=1/ωC

XL=ωL

Z=√(R^2 +(XL-Xc)^2)

tan φ = (XL-Xc)/R

ω=1/√LC

εmax=Imax*Z

## The Attempt at a Solution

I started out with Z=√(R^2 +(XL-Xc)^2) , and to get XL and Xc I used ω=2*pi*f .

I got my XL and Xc marked wrong. It wasn't a calculation mistake, so am I approaching the answer incorrectly?
