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

10.2 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)`.

In a meter bridge, as shown in the figure, it is given that resistance Y = 12.5 Omega and that the balance is obtained at a distance 39.5 cm from end A (by jockey J). After interchanging the resistance X and Y, a new balance point is found at a distance l_(2) from end A. What are the values of X and l_(2) ?

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]
