Each resistance of the network shown in ...

Each resistance of the network shown in figure is `r`. Net resistance between

A

`a` and `b` is `7/3r`

B

`a` and `c` is`r`

C

`b` and `d` is` r`

D

`b` and `d` is `r/2`

Text Solution

Verified by Experts

The correct Answer is:
B, D
Between `a` and `c`, balanced, Wheatstone bridge is formed. Across all other points simple series and parallel grouping of resistors.
