In a Wheatstone bridge, if the galvanometer shows zero deflection, what does it indicate?

In a Wheatstone bridge, if the galvanometer shows zero deflection, what does it indicate?

Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown electrical resistances.
Step 2: Know that a galvanometer is an instrument used to detect small electric currents.
Step 3: When the Wheatstone bridge is set up, it has four resistors and a galvanometer connected in a specific way.
Step 4: If the galvanometer shows zero deflection, it means there is no current flowing through it.
Step 5: Zero current indicates that the voltage across the galvanometer is zero.
Step 6: When the voltage is zero, it means the two sides of the bridge are equal in voltage.
Step 7: If the two sides are equal, the bridge is said to be balanced.
Step 8: Therefore, zero deflection in the galvanometer indicates that the Wheatstone bridge is balanced.
