Two identical capcitors `A` and `B` are charged to the same potential and then made to discharge through resistance `R_(A)` and `R_(B)` respectively with `R_(A) gt R_(B)`

A

`A` wil require greater time then `B` to discharge completely

B

More heat will be produced in `A` than in `B`

C

More heat will be produced in `B` than in `A`

D

All the above options are incorrect

Text Solution

Verified by Experts

The correct Answer is:
