A capacitor of capacitance C₁ charged up to V volt and then connected to an uncharged capacitor C₂ . Then, the final potential difference across each will be:

Options

  1. AC₂ V C₁+C₂
  2. BC₁ V C₁+C₂
  3. C(1+ C₂ C₁ ) V
  4. D(1- C₂ C₁ ) V

Correct answer

B. C₁ V C₁+C₂

Step-by-step solution

aligned & V_ comma = C₁ V₁+C₂ V₂ C₁+C₂ ( V₂=0 ) & V_ comma = C₁ V₁ C₁+C₂ aligned
