235. assignment (RLC circuit)

An RLC series circuit has a 4.00 kiloohms resistor, a 43 millihenry, and a 22 nano-farads capacitors.

a) Find the circuit’s impedance in ohms at 480 Hz

b)  Find the circuit’s impedance in ohms at 14.40 Hz

c) If the voltage source has Vrms=130V, what is in Amps the Irms at 14.40 kHz?

d)What is in Hz the resonant frequency of the circuit?

e) What is in ohms the impedance at resonance?
