A meter bridge is setup as shown in figure, to determine an unknown resistance `X` using a standard `10Omega` resistor. The galvanometer shows null point when tapping key is at `52 cm` mark. The end correctiosnn are `1 cm` and `2 cm` respectively for the ends `A` and `B`. The determined value of `X` is

A

`10.2Omega`

B

`10.6Omega`

C

`10.8Omega`

D

`11.11Omega`

Text Solution

Verified by Experts

The correct Answer is:
B
Using the concept of balance, Whetstone bridge, we have
`P/Q=R/Simplies X/((52+1))=10/((48+2))`
`:. X=(10xx53)/50=10.6Omega`
`:.` Correct options is b.
