Electrostatics Question 63
Question: A capacitor is kept connected to the battery and a dielectric slab is inserted between the plates. During this process [MP PMT 1994]
Options:
A) No work is done
B) Work is done at the cost of the energy already stored in the capacitor before the slab is inserted
C) Work is done at the cost of the battery
D) Work is done at the cost of both the capacitor and the battery
Show Answer
Answer:
Correct Answer: C
Solution:
In this process capacity increases, so battery supplies additional charge to capacitor.
