What is the purpose of the galvanometer in a Wheatstone bridge?

Correct Answer: Galvanometer ka purpose Wheatstone bridge mein balance condition ko detect karna hai.

Step 1: Understand that a Wheatstone bridge is a circuit used to measure unknown resistances.
Step 2: Know that the galvanometer is a device that can detect small electric currents.
Step 3: Realize that the Wheatstone bridge has four resistors arranged in a diamond shape.
Step 4: When the bridge is balanced, there is no current flowing through the galvanometer.
Step 5: The purpose of the galvanometer is to show whether the bridge is balanced or not by indicating if there is any current flow.
