Question

internal resiistance of cell depends upon

Answer 1

$\bigstar$ $\sf{\red{\underline{\underline{\purple{ANSWER:-}}}}}$

♻️ Internal Resistance of a cell depends upon ,

• The Surface Area of its electrodes .

• Separation between it's electrodes .

• Nature, Concentration and temperature of Electrolyte .

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

• On increasing temperature, in Electrolytes, there is increase in thermally generated electrons over the existing Ion's, so the internal resistance will decrease with the increase of temperature .
