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

A

10.2 ohm

B

10.6 ohm

C

10.8 ohm

D

11.1 ohm

Text Solution

Verified by Experts

The correct Answer is:
B
`l_(1) = 52 +1 = 53 cm`
`l_(2) = 48 + 2 =50 cm`
`(l_(1))/(l_(2))= (x)/(R)`.
