A series combination of resistor and capacitor is connected across with an applied A.C voltage source. Separate voltmeter readings across the resistor and capacitor give value of 50 V(r.m.s) and 75V(r.m.s) respectively. The effective r.m.s voltage of the source, is nearly a) 25 Vb) 90 Vc) 63 Vd) 125 VPls. show the steps.
