PhysicsElectrostatic Potential and CapacitanceMHT CET

Six identical capacitors, each of 1 F are joined in parallel and the combination is put across a battery of e. m. f. 2 V. Now, the battery is disconnected and the capacitors are joined in series. The total energy and potential difference across the series combination is

Answer: (D)

Solution

In parallel F and J; each capacitor keeps 2 V, so in series the p.d. adds to V while the energy
