Five resistors are connected as shown in the diagram. The equivalent resistance between `A` and `B` is

A

`6 ohm`

B

`9 ohm`

C

`12 ohm`

D

`15 ohm`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Since the given bridge is balanced, hence there will be no current through `9 Omega`. This resistance has no effect and must be ignored in the calculation.
`R_(AB) = (9 xx 18)/(27) = 6 Omega`
