In a potentiometer, what is the role of the jockey?
Correct Answer: Jockey ka role hai balance point dhoondhna.
- Step 1: Understand that a potentiometer is a device used to measure voltage.
- Step 2: Know that the jockey is a small metal contact that moves along a wire in the potentiometer.
- Step 3: The jockey is used to touch different points on the wire to find a specific voltage.
- Step 4: When the jockey touches a point where the voltage matches the reference voltage, we call this the balance point.
- Step 5: At the balance point, the potential difference across the wire is equal to the reference voltage, indicating a measurement.
