I am avidly awaiting your announcement of how some energy storage thing (aside from the obvious batteries) works in the circuits you're now ignoring.
Is a capacitor an energy storage device or not ? A battery converts chemical reaction in to electricity and some batteries are rechargeable meaning you can reverse the chemical reaction by supplying energy to the battery.
There is a good reason I insist in using a charged capacitor as the energy source in the circuit as understanding the capacitor is vital in understanding how electricity works.
Two neutrally charged parallel metal plates (say copper) with same number of free electrons as the number of atoms will represent a discharged capacitor.
There will be no electric field between the two plates.
Take a wire and connect those two plates together. Nothing will charge as the wire also say made of copper is also neutral has as many free electrons as the two capacitor plates.
Then get a permanent magnet and move it next to the wire. This will make the electrons move in one direction so one of the plates will have a deficit of electrons while the other plate an excess and since electrons have moved you will feel that force opposing the magnet while you are moving it so you spend some energy.
Part of this energy you introduced in the circuit will end up as heat (electromagnetic radiation) due to wire having resistance and some will be stored in the capacitor.
But as soon as you stopped moving the magnet the stored energy will be released as electrons now move in the opposite direction through the wire part of that energy ending up as heat and part reverse charging the capacitor but less energy as some was radiated as heat due to resistance. There may be a few cycles back and forth until all energy will be radiated as heat (electromagnetic radiation in the infrared spectrum so broad spectrum around a few THz).
If you move the magnet as before you stop disconnect the wire then the capacitor will remain charged and now you will have excess electrons on one plate and deficit of electrons on the opposite plate.
This excess electrons will really like to get on the other side to be united with their atoms thus this electric field that tries to pull the plates closer together.
The capacitor will stay charged so you have stored electrical energy and in order to use that energy you need a wire connecting the two plates.
Say you have the charged capacitor now and you connect a high resistance wire so that it takes say one hour for all electrons to move from one plate to the other.
If I add another similar wire just next to this one it takes just half the time so half an hour. Why will that be if electric field is the same ?
