Questions & Step-by-Step Solutions
If a galvanometer shows a deflection when connected to a potentiometer, what does it indicate?
Correct Answer: The potential difference across the galvanometer is equal to the reference voltage.
Step 1: Understand what a galvanometer is. It is a device that measures small electric currents by showing a needle deflection.
Step 2: Know what a potentiometer does. It is used to measure voltage by comparing it to a known reference voltage.
Step 3: When the galvanometer is connected to the potentiometer, it can show a deflection if there is a voltage difference.
Step 4: A deflection means that the voltage across the galvanometer is equal to the reference voltage provided by the potentiometer.
Step 5: Therefore, the deflection indicates that the two voltages are balanced.
Galvanometer and Potentiometer Relationship – A galvanometer measures current or voltage, and in this context, it indicates that the potential difference across it matches the reference voltage provided by the potentiometer.
Potential Difference – Understanding that a deflection in the galvanometer signifies a balance of potential difference is crucial for interpreting the results.
