WebJun 9, 2024 · 34.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.

Webthis experiment. You can also do step 1 in the Wheatstone Bridge section. Background The Wheatstone Bridge circuit can be used to measure an unknown resistance in terms of three known resistances by adjusting one or more of the known resistors to obtain a zero signal (i.e. a \null" reading) on a meter. Such a measurement permits high precision ... WebNov 10, 2024 · A meter bridge works on the principle of a Wheatstone bridge. A Wheatstone bridge is based on the principle of null deflection, i.e. when the ratio of resistances in the two arms is equal, no current will flow through the middle arm of the circuit. Consider the diagram of the Wheatstone bridge as shown below.
