AIPMT PRELIMS 2006 Physics Capacitors MCQ Question
A parallel plate air capacitor is charged to a potential difference of V volts. After disconnecting the charging battery the distance between the plates of the capacitor is increased using an insulating handle. As a result the potential difference between the plates:
decreases
does not change
becomes zero
increases
Correct Answer
Detailed Explanation
When the distance between the plates of a disconnected capacitor is increased, the capacitance decreases, leading to an increase in the potential difference.
