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
