Question
Two identical capacitors are connected in parallel and charged to a potential to V. They are separated and then connected in series. The potential across the series combination is -
Options
1
V
Correct Answer
2
4V
Correct Answer
3
3V
Correct Answer
4
2V
Correct Answer
Explanation
When connected in series (positive plate of one to negative of other), the individual voltages add up. Since each was charged to V, the total potential difference across the combination is V + V = 2V.
