Does internal resistance of a cell increase or decrease with increase in surface area? Could someone please explain... Thanks Share with your friends Share 0 Decoder_2 answered this Dear student,internal resistance of cell∝1surface areaIn cells ions are responsible for carrying electric current thus, larger is the surface area of the electrodes greater will be the number of ions reaching the electrodes and greater is the number of ions reaching electrodes higher will be the flow of current.We know greater is flow of current for a given potential lesser is its resistance, hence internal resistance of the cell will decrease with the increase in the surface area of the electrodes.Regards 1 View Full Answer
