```							Brother,                  emf is the potential difference of entire circuit. I.e. internet resistance of battery is also consider while calculating the emf.    emf is given by:-                             E=I/(R+r)            where R is externel resistance , r is internet resistance of battery. Voltage is the potential difference between two terminals of battery. I.e. internet resistance of battery will not considered while calculating voltage.        Voltage is given by:-                                    V=I/R

```							Emf is the voltage of the cell it is present even when no current is flowing ,whereas every component of a circuit can have different voltages  .also voltage does not exist in any component if current is not flowing in the circuit .
