Question

Internal resistance of cell depends upon..... A.. nature of electrolyte. B.. nature of electrodes. C.. distance between electrodes. D.. all

Answer 1

Hi

Here is your answer

Option D)All

Explanation:

Factors affecting internal resistace are:

• Distance between the electrodes: When distance increases, internal resistance decreases and vice versa.
• Nature, concentration and temperature of the electrolytes
• Nature of electrodes
• Area of electrodes: When area of electrodes increases,internal resistance  decreases and vice versa.

Notes:

1.The resistance offered by electrode and electrolyte of a cell when electric current flows through it is called internal resistance.

2.The equation of internal resistance is given by

r=(e-V)I

where e=Electromotive force, V=Potential difference across the cell ,I=current flowing through it.

3.Internal resistance depends on external resistance.
