If the Wheatstone bridge is unbalanced, what happens to the current through the galvanometer?

If the Wheatstone bridge is unbalanced, what happens to the current through the galvanometer?

Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown resistances.
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, there is no current flowing through the galvanometer.
Step 4: Learn that when the bridge is unbalanced, the resistances are not equal, which creates a difference in voltage.
Step 5: This difference in voltage across the galvanometer causes current to flow through it.
Step 6: Conclude that in an unbalanced Wheatstone bridge, the current through the galvanometer increases.
