Question
Question: When the dielectric slab enters in between the parallel plate capacitor then current- 
A
Flows from B to A
B
Flows from A to B
C
Infinite current flows
D
No current flows
Answer
Flows from B to A
Explanation
Solution
When dielectric is inserted more charge appears on capacitor plates. Hence plate A gets more +ve charge, which means +ve charge flows from B to A which is the direction of current.
