An ac circuit has a 20 ?F capacitor, an 80 mH inductor, and a 60 Ω resistor in series. If the voltage source has an angular frequency of 1000 rad/s, what is the phase constant for the circuit?
First calculate the reactance of the inductor and capacitor XL ωL 1000*80x10^-3 80Ω XC 1/ωC 1/(1000*20x10^-6) 50Ω So the phase constant φ arctan((XL - XC)/R) arctan((80-50)/60) 26.6o
