In a potentiometer setup, what is the role of the jockey?
Correct Answer: Jockey ka role hai wire ko touch karna aur null point dhoondhna jahan galvanometer zero deflection dikhata hai.
- Step 1: Understand that a potentiometer is a device used to measure voltage.
- Step 2: Know that the setup includes a long wire and a galvanometer.
- Step 3: The jockey is a small metal piece that can touch the wire.
- Step 4: Move the jockey along the wire to find a point where the galvanometer shows zero deflection.
- Step 5: This zero deflection means that the voltage across the wire at that point is equal to the voltage being measured.
- Step 6: This point is called the null point, indicating balance in the circuit.
