a) A resistor and capacitor are connected in series with an applied AC voltage source. Separate voltmeter readings across the resistor and capacitor give values of 50V and 75V (rms), respectively. What is the effective (rms) voltage of the source?
b) A 50 Ohm resistor, a 0.1-H inductor, and a 10-microF capacitor are connected in series to a 60-Hz source. The rms current in the circuit is 3 A. Find the rms voltage across the resistor, the inductor, and the capacitor. (Please show all steps for part A and B)
