Re: Difference between Voltage (Potential Difference) & EMF (Electromotive Force) ? t
The easiest way to understand the difference between "voltage difference" and "EMF" is consider a water flowing in a pipe line with obstacles in the way , consider a water pump pumps the water through a pipe line circuit , the water has initial pressure (p) at each obstacles it losses amount of it's pressure this amount let be (L) , after the obstacle the water's pressure will be (P-L), so (L) is the pressure difference between the two nodes of the obstacle . Now for electricity (p) will become (EMF) , (L) becomes(V), and the obstacles will become resistors , that's true they measured by the same unit but they are much different terms .
hope that really helps you
