Question 460: Electrostats & Capacitance

Question

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

Accepted Answer

Energy will remain the same due to conservation of energy
In case 1 , each capacitor is charged to p.d. V So, when they are connected in series, the p.d. will be nV

Answer

potential difference and total energy of the combination remain the same.

Answer

potential difference remains the same and energy increases n times.

Answer

potential difference becomes nV and energy remains the same.

Answer

potential difference is nV and energy increases n times.
