What is the advantages of using thick metallic strips to join wires in a potentiometer ?

Text Solution

Verified by Experts

In potentiometer, the thick metallic strips are used as they have negligible reistance and need not to be coounted in the length `l_(1)` of the null point of potentiomete. It is for the convenience of experiment as he measures only their lengths along the straight wires each fo lengths 1m. This measurements is done with the help of centimetre scale or metre scale with accuracy.
