You have an RLC circuit connected in series to an oscillating voltage source (e rms =120.0V ) which is driving it. R = 40.0Ω, L = 4.51mH, C = 1.56mF. The circuit is initially being driven at an angular frequency of 7460rad/s. (a)What is the impedance of the circuit? (b) What is the average power dissipated by the resistor? (c) What is the phase angle?

Question: You have an RLC circuit connected in series to an oscillating voltage source (e rms =120.0V ) which is driving it. R = 40.0Ω, L = 4.51mH, 
C = 1.56mF. The circuit is initially being driven at an angular frequency of 7460rad/s.
(a)What is the impedance of the circuit?
(b) What is the average power dissipated by the resistor?
(c) What is the phase angle?
(d)The inductor is removed and replaced by one such that the impedance 
increases by 20% with no other changes. What is the new inductance?
(e)What is the average power dissipated by the resistor now?
