STANDARD Physics Capacitors MCQ Question
A parallel plate capacitor is connected across a 2V battery and charged. The battery is then disconnected and a glass slab is introduced between plates. Which of the following pairs of quantities decreases?
Charge and potential difference.
Potential difference and energy stored.
Energy stored and capacitance.
Charge and energy stored.
Correct Answer
Detailed Explanation
When a dielectric like a glass slab is introduced between the plates of a disconnected capacitor, the capacitance increases, but the potential difference and energy stored decrease because the charge remains constant.
