प्रश्न
What is the advantage of using thick metallic strips to join wires in a potentiometer?
उत्तर
The metal strips have low resistance and need not be counted in the potentiometer length l1 of the null point. One measures only their lengths along the straight segments (of lengths 1 meter each). This is easily done with the help of centimeter rulings or meter ruler and leads to accurate measurements.
