Q
Q: In a potentiometer, what is the role of the jockey?
Solution:
The jockey is used to find the balance point where the potential difference is equal to the reference voltage.
Steps: 5
Show Steps
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.
