Internal resistance
of a cell
The electric current in an
external circuit flows from the positive terminal to the negative terminal of
the cell, through different circuit elements. In order to maintain continuity,
the current has to flow through the electrolyte of the cell, from its negative
terminal to positive terminal.During this process of flow by the electrolyte of
the cell. This is termed s the internal resistance of the cell.
A freshly prepared cell has
low internal resistance and this increases with ageing.
