✯e.m.f of a cell is the maximum value of potential difference between its electrodes when no current is being drawn from it .The em.f of a cell depends upon the following factors:--

● Nature of elctrodes.

●Nature of concentration of electrolyte.

●temperature of electrolyte used in cell.

here's your answer!!!☺☺

EMF of a cell: It is the energy required or work done to drive a unit charge to pass through the given circuit.
Emf of a cell is

-directly proportional to the distance of separation between the two electrodes

-inversely proportional to the area of electrodes dipped in electrolyte

-inversely proportional to the temperature of electrodes

-inversely proportional to the concentration of electrolyte.

1) Nature of the material of electrolyte
2) Internal resistance of the cell
3) Distance between the electrodes
