In a certain series RLC circuit being driven at a frequency of 60.0 Hz, the maximum voltage across the inductor is 2.50 times the maximum voltage across the resistor and 2.50 times the maximum voltage across the capacitor.
By what phase angle does the current lag the generator emf?
If the maximum generator emf is 31.0 V, what should be the resistance of the circuit to obtain a maximum current of 320 mA?
