Capacitors of capacities C₁ and C₂ are connected in series. If the combination is connected to a supply of V volt then the potential difference across capacitor C₂ is

Options

  1. AC₁ + C₂ C₁ V
  2. BC₁ V C₁ + C₂
  3. CC₁ + C₂ C₂ V
  4. DC₂ V C₁ + C₂

Correct answer

B. C₁ V C₁ + C₂

Step-by-step solution

In series combination, the equivalent capacitance is C_ eq = C₁ C₂ C₁ + C₂ . The charge on each capacitor is the same and is given by Q = C_ eq V = ( C₁ C₂ C₁ + C₂ ) V . The potential difference across capacitor C₂ is V₂ = Q C₂ . Substituting the value of Q , we get V₂ = C₁ V C₁ + C₂ .
