For resistances `10Omega, 10 Omega, 10 Omega and 15 Omega ` form a Wheatstone's network. What shunt is required across `15 Omega` resistor to balance the bridge ?

A

`10 Omega`

B

`15 Omega`

C

`20 Omega`

D

`30 Omega`

Text Solution

Verified by Experts

The correct Answer is:
D
For balancing `R_(4)` should be `10 Omega`
`=(1)/(S)=(1)/(10)-(1)/(15)=(1)/(30) therefore S=30 Omega`
