In a balanced Wheatstone bridge, the potential difference across the galvanometer is:

In a balanced Wheatstone bridge, the potential difference across the galvanometer is:

Correct Answer: zero

Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown electrical resistances.
Step 2: Know that a Wheatstone bridge consists of four resistors arranged in a diamond shape with a galvanometer connected between two points.
Step 3: Learn about the concept of 'balanced' in a Wheatstone bridge. It is balanced when the ratio of the resistances in one branch is equal to the ratio in the other branch.
Step 4: When the bridge is balanced, the current through the galvanometer is zero because there is no potential difference across it.
Step 5: Therefore, in a balanced Wheatstone bridge, the potential difference across the galvanometer is zero.

Wheatstone Bridge – A circuit used to measure unknown electrical resistances by balancing two legs of a bridge circuit.
Balanced Condition – Occurs when the ratio of resistances in one leg of the bridge equals the ratio in the other leg, resulting in zero potential difference across the galvanometer.
Galvanometer – An instrument used to detect and measure small electric currents, which shows zero reading in a balanced Wheatstone bridge.
