In the given circuit, the galvanometer G gives zero deflection. What is the value of resistance X ?

A

`10 Omega`

B

`12 Omega`

C

`15 Omega`

D

`20 Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
For this balanced wheatstone's network
`therefore (8)/(3)= (40)/(X) therefore X= 15 Omega`
