A capacitor of capacity 2 F is charged upto a potential 14 ~V and then connected in parallel to an uncharged capacitor of capacity 5 F . The final potential difference across each capacitor will be

Options

  1. A6 ~V
  2. B4 ~V
  3. C8 ~V
  4. D14 ~V

Correct answer

B. 4 ~V

Step-by-step solution

When two capacitors are connected then their common potential difference is aligned V= C₁ V₁+C₂ V₂ C₁+C₂ Given, C₁ & =2 F , V₁=14 ~V , C₂=5 F , V₂=0 ~V V= 2 14+5 0 2+5 =4 ~V aligned
