31.14. You have a 200-resistor, a 0.400-H inductor, and a 6.00-1F capacitor. Suppose you take the resistor and inductor and make a series circuit with a voltage source that has voltage amplitude 30.0 V and an angular frequency of 250 rad/s. (a) What is the impedance of the circuit? (b) What is the current amplitude? (c) What are the voltage amplitudes across the resistor and across the inductor? (d) What is the phase angle of the source voltage with respect to the current? Does the source voltage lag or lead the current? (e) Construct the phasor diagram.
