Question
If each of the resistances in the network in figure R, the equivalent resistance between terminals A and B is
- 5 R
- 2 R
- 4 R
- R
The correct answer is: R
When cell is connected to points A and B no current will flow in the resistance of arm PQ. Effective resistance of arm APS will be in parallel to the total resistance of arm AQS
\ Equivalent resistance=
