A capacitor is charged by a cell of emf

E

and the charging battery is then removed. If an identical capacitor is now inserted in the circuit in parallel with the previous capacitor, the potential difference across the new capacitor is

View answer and explanation

Correct option: C

E / 2

Option C (

E / 2

) is correct because when an identical capacitor is added in parallel, the charge is distributed equally, halving the potential difference.
