In a Wheatstone bridge, if the galvanometer shows a current, what can be inferred?

In a Wheatstone bridge, if the galvanometer shows a current, what can be inferred?

Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown resistances.
Step 2: Know that a Wheatstone bridge has four resistors arranged in a diamond shape.
Step 3: Recognize that a galvanometer is a device used to detect current in the circuit.
Step 4: When the bridge is balanced, no current flows through the galvanometer.
Step 5: If the galvanometer shows a current, it means there is a difference in voltage across the two sides of the bridge.
Step 6: This difference indicates that the resistors are not equal, meaning the bridge is unbalanced.
