    the definition of EMF is the amonut of electrical energy converted from other forms of energy per unit charge.

    if you are wondering whats the diff from PD, then the definition of PD is the amount of electrical energy converted into other forms of energy.

    Basically emf is the force that pushes the electron around the curcuit.
