In the diagram below each resistance is of `1 Omega`. The total resistance between A and B is

A

`3//8Omega`

B

`3//5Omega`

C

`2//8Omega`

D

`5//7Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
In figure, four resistance are in parallel, Thus, there effective resistance is ,
`(1)/(R_(p))=1/1 + 1/1+ 1/1+1/1=4/1`
`:.R_(p)=1/4=2/8 Omega`
