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 a metal increases with increase in temperature.
Statement-2 : Resistance of a metal increases with increase in temperature.
