Find the effective resistance between A and B.

A

`2 Omega`

B

`1Omega`

C

`8//7 Omega`

D

`7 Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
c. `R_(equal) = (8/3 xx 2)/(8/3 +2) = 16/14 = 8/7 Omega`
The charge x passing between A and D will entirely pass to DA2. So, we can detach the circuit at point D and shown in figure.
