Let's say we have a source of electrical energy, in form of a battery or some other source. We then connect a load to it. The source creates a potential difference across the load and drives a certain amount of current through it. The amount of current depends on the load. We know that, current is just a flow of electrons and the electrons leave the source at one end and then enter back into the source at the other end. Now, what is it that delivers power to the load. I want to know how the transfer of power or energy is taking place here. What do electrons loose in this process and how does the source fill the electrons with the capacity to do it. If the current leaving the source and the current entering the source are equal what is lost there?
