Hello candidate,

Aur wheatstone bridge is an electrical representation of resistors connected to a battery and other electrical measurement units such as ammeter and voltmeter. A galvanometer is connected across two resistors connecting both its forming the ideal condition for a wheat stone bridge.

In an ideal wheatstone bridge, the current flowing through the galvanometer is zero and thus the galvanometer can be neglected and the net resistance through the wheatstone bridge comes out to be R, where (R1/R3= R2/R4).

Hope that it helps you!!
