Two condensers C ₁ & C ₂ in a circuit are joined as shown in the figure. The potential of point A is V₁ and that of point B is V₂ . The potential at point D will be

Options

  1. A1 2 ( ~V ₁+ V ₂ )
  2. BC₂ V₁+C₁ V₂ C₁+C₂
  3. CC₁ V₁+C₂ V₂ C₁+C₂
  4. DC₂ V₂-C₁ V₂ C₁+C₂

Correct answer

C. C₁ V₁+C₂ V₂ C₁+C₂

Step-by-step solution

In series combination, Q ₁= Q ₂ C₁ (V₁-V )=C₂ (V-V₂ ) V ( C ₁+ C ₂ )= C ₁ ~V ₁+ C ₂ ~V ₂ ~V = C ₁ ~V ₁+ C ₂ ~V ₂ C ₁+ C ₂
