Question

Which is the factor that internal resistance does not depend on?

(a) Distance between the electrodes

(b) Temperature of the electrolyte

(c) Nature of electrode and electrolyte

(d) Area of the electrode, immersed in the electrolyte

This question was addressed to me in quiz.

My question comes from Current Electricity in section Current Electricity of Physics – Class 12

Answer 1

The correct choice is (b) Temperature of the electrolyte

The best explanation: Internal resistance is defined as the resistance offered by the electrolyte and electrodes of a cell when the current flows through it. Internal resistance depends on distance between the electrodes, the nature of electrodes and electrolyte, and area of the electrode immersed in the electrolyte. So, that leaves temperature of the electrolyte out, which is the answer.
