STANDARD Physics Capacitance MCQ Question
Type: MCQ-numerical-Medium
Two condensers, one of capacity C and other of capacity C/2 are connected to a V volt battery, as shown in the figure. The work done in fully charging 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 capacitors are connected in parallel, so the potential difference remains the same. The total charge q = q₁ + q₂ = CV + (C/2)V = (3/2)CV. The work done W = 1/2 qV = 3/4 CV².
