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

Options:

Correct Answer: The bridge is unbalanced

Solution:

A deflection in the galvanometer indicates that the bridge is unbalanced, meaning the ratios of the resistances are not equal.

Correct Answer: Bridge is unbalanced.

Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown resistances by balancing two legs of a bridge circuit.
Step 2: Know that a galvanometer is an instrument used to detect and measure small electric currents.
Step 3: When the Wheatstone bridge is balanced, the current through the galvanometer is zero, and it shows no deflection.
Step 4: If the galvanometer shows a deflection, it means there is a current flowing through it.
Step 5: A current flowing through the galvanometer indicates that the two legs of the bridge are not balanced.
Step 6: The unbalance means that the ratios of the resistances in the two legs of the bridge are not equal.

Wheatstone Bridge – A circuit used to measure unknown electrical resistances by balancing two legs of a bridge circuit.
Galvanometer Deflection – Indicates the presence of a voltage difference between the two sides of the bridge, signifying an imbalance.
Resistance Ratios – The principle that the bridge is balanced when the ratio of resistances in one leg equals the ratio in the other leg.
