AIPMT PRELIMS 2007 Physics Capacitors MCQ Question
Type: MCQ-numerical-Medium-Class 12
Two condensers, one of capacity C and other of capacity C/2 are connected to a V⁻volt battery, as shown. The work done in charging fully both the condensers is
A
1/4 CV²
B
3/4 CV²
C
1/2 CV²
D
2CV²
Correct Answer
Option B
Detailed Explanation
The total work done is the sum of the energy stored in both capacitors: W = 1/2 C V² + 1/2 (C/2) V² = 3/4 CV².
