STANDARD Physics Capacitors MCQ Question
Type: MCQ-conceptual-Medium
A capacitor of capacitance C₁ is charged to a potential V and then connected in parallel to an uncharged capacitor of capacitance C₂. The final potential difference across each capacitor will be
A
C₂V / (C₁ + C₂)
B
C₁V / (C₁ + C₂)
C
1 + C₂ / C₁
D
1 - C₂ / C₁
Correct Answer
Option A
Detailed Explanation
When a charged capacitor of capacitance C₁ is connected in parallel to an uncharged capacitor of capacitance C₂, the charge is shared between them till both attain the common potential which is given by, common potential = (C₁V) / (C₁ + C₂).
