# series RLC circuit

I am having trouble with #27, I need a mapped out way to get the answers to match the back of the book.

Note: you need to use the RLC circuit in # 14 (the one in the right column) to obtain the answers in#27

27. Consider the series RLC circuit of problem 14. The voltage amplitude of the source is 150 V.

(a) At what angular frequency is the circuit resonance?

(b) Sketch the phasor diagram at the resonance angular frequency.

c) What is the reading of each voltmeter in Figure 22.22 when the source frequency equals the resonance voltages.

d) What is the resonance angular frequency if the resistance is reduced to 100 ohms?

e) what is then the rms current at resonance?
