Question

Factors affecting internal resistance of a cell experiment class 12

Answer 1

I an in clad 10 but I believe I can give you an answer
: the resistance if a circuit is affected by :-
potential difference
temperature
material of the conductor and hence it's resistivity
current passing through the cross section
area of the wire
length of the wire

all these affect the resistance of the circuit

Answer 2

Factors affecting internal resistance of a cell :

(1) Larger the separation between the electrodes of the cell, more the length of the electrolyte through which current has to flow and consequently a higher value of internal resistance.

(2) Greater the conductivity of the electrolyte, lesser is the internal resistance of the cell. i.e., Internal resistance depends on the nature of the electrolyte.

(3) The internal resistance of an electrolyte is inversely proportional to common area of the electrodes dipping in the electrolyte.

 (4) Internal resistance of a cell depends on the nature of the electrolytes.
