⏩Greater the conductivity the electrolyte, lesser the internal resistance of the cell i.e; internal resistance depends on the nature of the electrolyte.The internal resistance of A cell is inversely propotional to the common area of the electrodes dipping in the electrolyte.

A practical electrical power source which is a linear electric circuit may, according to Thévenin's theorem, be represented as an ideal voltage source in series with an impedance. This impedance is termed the internal resistance of the source. When the power source delivers current, the measured voltage output is lower than the no-load voltage; the difference is the voltage drop (the product of current and resistance) caused by the internal resistance. The concept of internal resistance applies to all kinds of electrical sources and is useful for analyzing many types of electrical circuits.
