The equivalent resistance between A and ...

The equivalent resistance between A and B in fig. at steady state will be

A

2r

B

`(3)/(5)r`

C

`(5)/(3)r`

D

none of the above

Text Solution

Verified by Experts

The correct Answer is:
A
At t= 0, the potential difference across the top `2muF` capacitor
is 0. Therefore, `I = 10//2 = 5A`.
