In the arrangement of resistances shown below, the effective resistance between points A and B is-

A

`20 Omega`

B

`30 Omega`

C

`90 Omega`

D

`110 Omega`

Text Solution

Verified by Experts

The correct Answer is:
A
By concept of balanced Wheatstone bridge-

`R_(eq) = (30 xx 60)/90 = 20 Omega`
