Seven resistances are connected as shown...

Seven resistances are connected as shown in the figure. The equivalent resistance between A and B is-

A

`3 Omega`

B

`4 Omega`

C

`4.5 Omega`

D

`5 Omega`

Verified by Experts

The correct Answer is:

B

This is balanced Wheatstone bridge
As no current passes through `8 Omega` resistance.
`R_(AB) = (8 xx 8)/16 = 4 Omega`
