Q: If the Wheatstone bridge is unbalanced, what can be inferred about the potential difference across the galvanometer?

Solution: An unbalanced Wheatstone bridge will have a non-zero potential difference across the galvanometer.

Steps: 5

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 the Wheatstone bridge has four resistors and a galvanometer (a device that measures current).
Step 3: Recognize that when the bridge is balanced, the potential difference across the galvanometer is zero, meaning no current flows through it.
Step 4: Learn that if the Wheatstone bridge is unbalanced, it means the resistances are not equal, causing a difference in voltage.
Step 5: Conclude that this difference in voltage results in a non-zero potential difference across the galvanometer, indicating that current will flow through it.
