Initially n identical capacitors are joined in parallel and are charged to potential V . Now they are separated and joined in series. Then

Options

  1. APotential difference becomes n V and energy remains the same.
  2. Bpotential difference is n V and energy increases n times
  3. Cpotential difference total energy of combination remains same
  4. Dpotential difference remains the same and the energy increases n times.

Correct answer

A. Potential difference becomes n V and energy remains the same.

Step-by-step solution

Charge will not flow and potential difference across each capacitor will be V . Hence, total potential difference across the series combination will be n V . Total energy will remain same as charge is not flowing.
