What is the role of the jockey in a potentiometer?
Correct Answer: Jockey ka role potentiometer mein null point dhoondhna hai.
  • Step 1: Understand that a potentiometer is a device used to measure voltage.
  • Step 2: Know that the jockey is a movable contact that touches the wire of the potentiometer.
  • Step 3: Move the jockey along the wire to find a point where the voltage is balanced.
  • Step 4: This balanced point is called the null point, where no current flows through the galvanometer.
  • Step 5: The position of the jockey at the null point helps measure the unknown voltage accurately.
