Question

Internal resistance of cell does not depend upon the
(a) current taken by cell
(b) distance between the electrode
(c) concentration of electrolyte
(d) emf of cell

Answer 1

d option is correct, it does not depend on emf

Answer 2

Internal resistance of cell does not depend upon the emf of cell.

Explanation:

Internal resistance defined as the opposition to the flow of current by the cells and batteries and resulting in the generation of heat.

It is measured in ohm.

Internal resistance cell depend on:

1. Depend on the surface area of the electrodes.
2. Depend on the distance between the electrodes.
3. Depend on current taken by cell.
4. Depend on concentration of electrolyte.
5. Depend on nature and temperature of electrolyte.

E.m.f. of a cell basically depends upon the material of electrodes and electrolyte used in the cell and its not a factor of Internal resistance.

Hence,

Option (d) emf of cell is correct.
