How to do Meter Bridge Experiment | Class 12
AIM
To determine the resistance of a given wire using a metre bridge and hence determine the resistivity of the material of the wire.
APPARATUS AND MATERIAL REQUIRED
Metre bridge, a wire about 1m long (of material whose specific resistance is to be determined), a resistance box, a rheostat, galvanometer, a jockey, one-way key, a cell or battery eliminator, thick connecting wires, sand paper, screw gauge.
In this video, you will learn a practical method to determine the resistance of a wire using a meter bridge, which operates based on Wheatstone's principle and also check out the readings in the observation table. The meter bridge consists of four resistors, namely P, Q, R, and S, connected to form the network ABCD. To start the experiment, connect terminals A and C to a battery and terminals C and D to a galvanometer through keys K1 and K2, respectively.
The objective is to achieve a balancing condition, where there is no deflection on the galvanometer. When the bridge is balanced, it follows the condition P/Q = R/S. By adjusting the known resistances P, Q, R, and S, you can find the specific resistance of the given wire.
Through this video, you'll gain a comprehensive understanding of how to perform the experiment and a procedure to find the resistance of a given wire using a meter bridge and hence determine the specific resistance of its materials.

About Metre bridge:
It consists of one metre long constantan wire of uniform cross-sectional area mounted on a wooden board with a scale. The two ends of the wire are attached to the two extreme terminals. Thick metal strips bent at right angles are used to provide two gaps to connect resistors forming a Wheatstone’s bridge. The terminal between the gaps is used for connecting galvanometer and other end of the galvanometer is connected to a jockey.
