A cell of internal resistance 1.5 Ω Ω and of e.m.f. 1.5 volt balances 500 cm on a potentiometer wire. If a wire of 15 Ω Ω is connected between the balance point and the cell, then the balance point will shift
Text Solution
Verified by ExpertsThe correct answer is:
D
Balance point has some fixed position on potentiometer wire. It is not affect by the addition of resistance between balance point and cell.
