The thing with EMF is that it is more to do with currentless voltage like the charge on a cap When I went to school, EMF (E) was the source of voltage in a circuit (battery, generator). V=IR applied to the voltage drop across resistive components within the circuit in question.

One of the best ways to understand an abstract like electricity is to conceptionalise it in the terms of water moving through pipes: Where voltage then becomes the pressure moving the water & the current is then the volume of water moving through the pipes. So if you raise the pressure (V), this then in turn increases the current (I) through the same resistance (R). Not complex at all. That looks like how Wa2ise was taught, as I was.
