Question

Two identical air capacitors A and B of the parallel plate type are charged to the same potential and connected in parallel (+ to +). Now a dielectric is inserted between the plates of A, then

• A. Charge flows from A to B
• B. Charge flows from B to A
• C. No charge flows either way
• D. Charge may flow from A to B or vice versa depending on the K of the dielectric

Answer 1

The correct option is B

Charge flows from B to A

On inserting dielectric in A its capacity increases, but still A and B are parallel with a common potential difference across. More capacity needs more charge, hence the flow of charge is from B to A
