In a potentiometer experiment, if the balance point shifts when a load is connected, what does it indicate?
Correct Answer: Load connected se balance point shift hota hai.
- Step 1: Understand what a potentiometer is. It is a device used to measure voltage by comparing it to a known voltage.
- Step 2: Know that the balance point is where the voltage across the potentiometer wire matches the voltage of the source being measured.
- Step 3: When a load (like a resistor or device) is connected to the circuit, it changes the total resistance in the circuit.
- Step 4: This change in resistance affects the current flowing through the circuit.
- Step 5: As the current changes, the potential difference (voltage) across the potentiometer wire also changes.
- Step 6: If the balance point shifts, it means the voltage across the potentiometer wire is no longer equal to the source voltage due to the load.
- Step 7: Therefore, a shift in the balance point indicates that the load is affecting the circuit's total resistance and the voltage distribution.
