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.
tan φ = (XL-Xc)/R
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?
