In a certain series RLC circuit being driven at a frequency of 60.0 Hz, the maximum voltage across the inductor is 2.00 times the maximum voltage across the resistor and 2.00 times the maximum voltage across the capacitor. (a) By what angle does the current lag the generator emf? (b) If the maximum generator emf is 30.0 V, what should be the resistance of the circuit to obtain a maximum current of 300 mA?

Question

In a certain series RLC circuit being driven at a
frequency of 60.0 Hz, the maximum voltage across the inductor
is 2.00 times the maximum voltage across the resistor and 2.00
times the maximum voltage across the capacitor. (a) By what angle
does the current lag the generator emf? (b) If the maximum generator
emf is 30.0 V, what should be the resistance of the circuit to
obtain a maximum current of 300 mA?
