  1. i think E.M.F is the voltage of cell when no load is connected , but P.D is the term applied when the cell is connected to the load.

    1. @ y.hemanth kumar
      potential difference is same as voltage/voltage drop,as the case may be…..

      E.M.F is gotten when supply is not connected to load (i.e in an open circuit) while ;
      Potential Difference/Voltage drop is gotten when supply is connected to load (i.e in a closed circuit)

      i hope this helps.
