1. The problem statement, all variables and given/known data In a circuit, a capacitor (Xc=30Ω, R=44Ω) and an inductor (Xl=90Ω, R=36Ω) are connected in series with an AC source (ƒ=60Hz, V=200V). Determine: 1-current intensity 2-the voltage across every component in the circuit. 2. Relevant equations Z=√R²+(Xl-Xc) Where: Z is the impedance, Xl is the inductive reactance, and Xc is the capacitive reactance. I=V/Z 3. The attempt at a solution That is how I solved the problem: And that is how my text book solved it: I get confused when I saw it, because I don't know why it consider the resistance of the capacitor to be an independant resistance while it didn't do with the resistance of the inductor, and determined the equivalent impedance of it, and consequently, it determined the potential difference across the inductor as 193.86V and not 180V as I did. Could someone explain it for me?
