MHT CET Physics question
A variable capacitor and an inductive coil with negligible resistance are connected in series to an A.C. voltage of value 100 V. The current in the circuit is 5 A. When the capacitor decreases to half its value, the current becomes 10 A. The voltage across the capacitor, in first case, is
