I think a conductor using protons would transfer more energy at the same current. Conversely, if we accelerated electrons and protons in a vacuum across an equal (but opposite) p.d., they would both acquire the same kinetic energy, but the electrons would reach a higher speed and create a larger...

Thanks again Andrew. So, you are saying that the energy transferred to the electrons in a circuit is entirely as kinetic energy, but that it is not just as the extra kinetic energy caused by the drift velocity, if I understand correctly. Regarding the electric field/p.d. question. It seems...

Thanks for your reply Andrew, very kind. However, I'm not sure we've really got to the bottom of my question. As I mentioned, I worked out the KE of all of the electrons in a piece of wire carrying a certain current using their drift velocity and the charge carrier density for copper. For the...

Hi there, Sorry if this is in the wrong section. I'm currently doing some work on models for electric circuits, but my own are not particularly complete! If anyone could shed some light on the following, I would be very grateful: How do the electrons transfer the energy in a circuit...
