Question

An RLC circuit consists of a resistor, a 1.00-μF capacitor, and a 250-mH inductor. If it is driven by an ac voltage source whose frequency is 60 Hz,
(a) What is the impedance of an RLC circuit at resonance?
(b) How does its impedance compare to that in part (a) if the source frequency is doubled: is it more, less, or the same value?
(c) How does its impedance compare to that in part (a) if the source frequency is halved; is it more, less, or the same value? Explain your reasoning for all parts.
