17. Consider a series RLC circuit consisting of a 3.4 ̐ resistor, a 8.6 10^-3 H inductor, and a 5.62 10^-3 F capacitor. The circuit is driven by a rms emf of 220 V running at 50 Hz. a) What is the impedance of the circuit? b) Let the current at any instant in the circuit be I(t) = I_0 sin(̐t - ̕). Find I_0. c) What is the phase angle between the generator voltage and the current?
