Physics 2: RLC Circuits

A 40 uF capacitor is in series with a 100 mH inductor, a 30 ohm resistor, and a 15V AC signal with a frequency of 60Hz. (a) Calculate the capacitive reactance and the inductive reactance in the circuit. (b) Determine the impedance. (c) Calculate the rms current in the circuit. (d) Calculate the voltage across the resistor, the inductor, and the capacitor. (e) How much power is consumed in the circuit? (f) What is the resonant frequency of the circuit?

Before the switch is closed, the capacitor is uncharged and all currents are zero.

B. A long time after the switch is closed, find the voltage drop across and the current through the capacitor, inductor, and resistor.

What are the maximum voltage drops across each element? What is the average power dissipated in the circuit?
