Question

state the principle of working of potentiometer. in the potentiometer arrangements, the cell emf is 12V gives the balance point at 30 cm length of the wire. the cell is now replace by the another cell of unknown emf if the ratio of the emf of two cells is 1.5, calculate the difference in the balancing length of the petionmeter wire​

Answer 1

Answer:

Difference in the balancing length of potentiometer wire is 10 cm.
