Question

A cell of internal resistance 1.5 ohm and of emf 1.5 volt balance is 500 cm on a potentiometer wire if a wire of 15 ohm is connected between the balance point and the cell in the balance point will shift to how much.Mppmt 1998

Answer 1

Answer:

Explanation:

=> It is given here,

internal resistance of a cell = 1.5 ohm

emf of cell = 1.5 volt

balance = 500 cm

=> a wire of 15 ohm is connected between the balance point and the cell

As a result, balance point is not affected if any resistance wire is connected between the balance point and the cell and it has some fixed position on potentiometer wire.

Thus, the balance point will not shifted.

Answer 2

Answer:

no shift.

Explanation:

in balance condition no current flows in the galvanometer circuit hence there will be no shift in balance point after connecting a resistance between balance point and cell.
