Quiz 10 -- ac Circuit

Consider an RLC series circuit (30 ohm, 250 mH, 20 microF) driven at 115 Vrms, 60 Hz.

a. What is the current in this circuit?

b. What frequency would bring this circuit into resonance?

c. Alternatively, what capacitance added in parallel to the existing capacitor would bring this circuit into resoance at 60 Hz?

d. What is the current at resonance?
