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.

Statement-1 : In a Meter Bridge experiment, null point for an unknown resistance is measured. Now, the unknown resistance is put inside an enclosure maintained at a higher temperature. The null point can be obtained at the same point as before by decreasing the value of the standard resistance. Statement-2 : Resistance of metal increases with increase in temperature.

The circuit diagram given in the figure shown the experimental setup for the measurement of unknown resistance by using a metre bridge. The wire connected between the points P and Q(PQ = 100 cm) has uniform cross-sectional area and its resistivity is directly proportional to the distance from point P. Null point is obtained with the jockey J with R_1 and R_2 in the gaps. If R_1 and R_2 are interchanged, the jockey has to be displaced through a distance from the previous position along the wire to establish the null point. If the ratio of R_1/R_2=3 , the value of Delta (in cm) is: [Ignore any end corrections]
