Question

What do you mean by Wheatstone bridge? Discuss its balanced condition.​

Answer 1

A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridgecircuit, one leg of which includes theunknown component.

Answer 2

Hey dude,

Wheatstone Bridge: a simple circuit for measuring an unknown resistance by connecting

it so as to form a quadrilateral with three known resistances and applying a voltage between a pair of opposite corners.

Balanced Condition: Practically, the variable resistance is adjusted till the value of current through the galvanometer becomes zero.

At that point, the bridge is called as balanced Wheatstone bridge.

Getting zero current through galvanometer gives high accuracy, as a minor change in variable resistance can disrupt the balance condition.
