Current is the flow of charges (many say electrons).
Do these charges flow just between the terminals of the source/battery (terminal to terminal) ?
Do these charges flow through/inside the source/battery as well?
What I know is that the positive terminal is the lack of electrons as compared to the negative terminal which is the excess of electron.
Current flows when electrons flow from the negative terminal of the battery to the positive terminal of the battery/source?
My question is what happens when the electrons reach from the negative terminal to the positive terminal? Are electrons then "absorbed" by the positive charges or they continue to flow through the source/battery to move in cycles?
