" Wheatstone bridge "r

Write the Wheatstone bridge principle.

Why circuit given by Wheatstone is called Wheatstone bridge ?

What is a Wheatstone bridge ?

In the following Wheatstones bridge P//Q=R//S . If key K is closed then the galvanometer will show deflection

In the following Wheatstone bridge P//Q = R//S . If key K is closed, then the galvanometer will show deflection

With the help of a labelled diagram, show that the balancing condition of a Wheatstone bridge is : (R_(1))/(R_(2))=(R_(3))/(R_(4)) where the terms have their usual meaning.

What is Wheatstone bridge? Deduce the condition for which Wheatstone bridge is balanced.

A Wheatstone's bridge is shown in figure. The condition for balancing the bridge is
