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

In a Wheatstone bridge, if the galvanometer shows a current, 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 Wheatstone bridge has four resistors and a galvanometer (a device that detects current).
Step 3: When the bridge is balanced, no current flows through the galvanometer.
Step 4: If the galvanometer shows a current, it means there is a difference in resistance between the two sides of the bridge.
Step 5: This difference indicates that the bridge is unbalanced, meaning the resistances are not equal.
