1. The problem statement, all variables and given/known data 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. 2. Relevant equations Xc=1/ωC XL=ωL Z=√(R^2 +(XL-Xc)^2) tan φ = (XL-Xc)/R ω=1/√LC εmax=Imax*Z 3. 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?
