Assertion (A) In a meter bridge experiment, null point for an unknown resistance is put inside an enclosure maintained at a higher temperature. The null point can be obtained at the same p as before by decreasing the value of the standard resistance. Reason (R) Resistance of metal increases with increase in temperature.
