In a cell current flows from positive to negative, then where is the loss of current when it again reach to the cell or battery

The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. As per the Ohm’s Law, the current is proportional to the electric field, which says that current flows from a positive to negative electric potential.
