Sorry if the title is slightly misleading, but I'm having a hard time trying to develop a better understanding of electric current and electrical energy. Basically, I understand that, say for example, a potential difference across a circuit creates an electric field, which in turn causes the electrons in a copper wire (for this example) to move in the direction of the electric field. The higher the difference, the greater the force that acts on the electrons.
Here is where I have some trouble- what actually IS electrical energy? Like, I understand that the electrons start to move (very slowly), but what actually performs work? It's not the movement of the electrons, as that would be kinetic energy, and the mass of an electron is extremely small, so collisions with atoms wouldn't amount to much, right?.
I guess a better way to phrase my question(s) would be "What is it about the flow of electrons that has the ability to do work, whether it be light a light bulb, create heat, etc.? Why does a flow of electrons create electrical energy? How is this energy then put to a practical use?" If my question's reveals misunderstandings, please by all means point it out, I've been toying with this for awhile now.
Thanks
