Question

Internal resistance of a cell is:

पर्याय

• inversely proportional to the surface area of electrodes in contact with electrolyte

• directly proportional to the distance between the electrodes

• dependant on the temperature of electrolyte

• all of these

Answer 1

All of these

Explanation:

Internal resistance decreases when the surface area of electrodes in contact with the electrolyte increases, increases with the distance between electrodes, and also depends on the nature, concentration and temperature of the electrolyte. So all three statements are correct.
