# What is the principle of meter bridge- meter bridge in hindi The meter bridge is a device based on the principle of Wheatstone. With the help of which the conductor can find the resistance of the wire.Use of meter bridge is also unknown re

## Description of meter bridge equipment-

The meter bridge is displayed as shown in it, there is a 1 meter long manganine wire A C which is supported by 1 meter scale. The two ends of this wire are joined by thick L-shaped brass leaves.

There are two spaces A B and C B between these leaves. Unknown resistance X is placed in one blank space A B and in other spaces (C D) resistance box R B is placed. Leclic cell between A and C points and

## theory-

It is based on the principle of the Wheatstone Bridge. The bridge is said to be in a balanced state when there is no deflection in the thermometer by pressing the jockey D on the bridge wire while plugged into the key K. Then point B and

In this case, the resistance of the meter bridge between X / R = A and D / the resistance of the meter bridge wire between D and C, X / R = lx / (100 – l) x, x / R = l / (100 – l), x = R l / (100 – l), so we can
