A condenser is charged to double its initial potential. The energy stored in the condenser becomes x times, where x = ……
The energy stored in a condenser is proportional to the square of the potential. When the potential is doubled, the energy increases by a factor of four. Hence, the correct answer is 4 times, corresponding to option (b) 4.

The correct answer is (b) 4.
The energy stored in a capacitor is given by U = (1/2) C V². When the potential V is doubled, the new energy becomes U’ = (1/2) C (2V)² = (1/2) C × 4V² = 4U. Thus, the energy stored in the capacitor increases 4 times its initial value.
