Q
Q: In a Wheatstone bridge, if the galvanometer shows zero deflection, what can be inferred about the current?
Solution:
Zero deflection indicates that no current flows through the galvanometer.
Steps: 5
Show Steps
Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown resistances.
Step 2: Know that a galvanometer is a device that detects current flow in the circuit.
Step 3: When the galvanometer shows zero deflection, it means the needle is not moving.
Step 4: If the needle is not moving, it indicates that there is no current flowing through the galvanometer.
Step 5: Therefore, we can conclude that zero deflection means no current is flowing.
