A capacitor is charged by a cell of emf `E` the chaging battery is then removed. If an identical capacitor is now inserted in te circuit in parallel with the prevous capacitor, the potential difference across the new capacitor isA. `2E`B. `E`C. `E/2`D. zero |
|
Answer» Correct Answer - C common potential in parallel grouping `=("Total charge")/("Total capacity")` `(EC)/(2C)=E/2` |
