The plates of parallel plate capacitor is connected by a battery of emf V0. The plates are lowered into a vessel containing a dielectric liquid with constant velocity v. Then –
A
Capacitance gradually decreases
B
Current is drawn from battery
C
Potential difference between plates decreases
D
The charge on plates decreases
Answer
Current is drawn from battery
Explanation
Solution
When capacitor is lowered, capacitance increases and there by charge on plates will increase hence current will be drawn from battery.
