A parallel plate capacitor of capacitance C 1 with a dielectric slab in between its plates is connected to a battery. It has a potential difference V 1 across its plates. When the dielectric slab is removed, keeping the capacitor connected to the battery, the new capacitance and potential difference are C 2 and V 2 respectively. Then,
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
The capacitance of a capacitor decreases when the dielectric is removed.
With dielectric, capacitance,
On removing dielectric, capacitance,
Therefore, .
Also, battery is not removed, thus,
