I'd like to know if I am understanding correctly that in the example, where a copper rod is bent into a ring and spliced into it are the battery and a light bulb, the light bulb filament is heated by two forces simultaneously:
[Exhibit A] the friction from the Coulombs and the [Exhibit B] the friction resulting from the electrical energy that forces itself through the flow of Coulombs (which may or may not move against the electrical energy.
This leads leads me wondering which of the forces create greater friction on their own and if there are instances where only one of the frictional forces are present and not the other.
Exhibit A: "Make another cut in the metal ring, install a light bulb in the cut, and then the "friction" of the narrow light bulb filament against the flowing charge-stuff creates high temperatures, and the wire filament inside the bulb glows white-hot. The battery drives the ring of charge into motion, the charge moves along like a drive belt, and the light bulb "rubs" against the moving charge, which makes the filament grow hot.

Exhibit B:"For example, whenever a battery powers a light bulb, the battery spews electrical energy into space! The electrical energy is then grabbed firmly by the wires and guided by them. The energy flows parallel to the wires, and eventually it dives into the light bulb filament. There it drives the metal's charges against the resisting force of electrical "friction," and the electrical energy gets converted into thermal energy. " http://amasci.com/elect/poynt/poynt.html
I absolutely love William J. Beaty's explinations. I found them more useful that anything I have ever read in many years of atemptiong to study electricity. He provides the only form of information on this complex subject that my mind accepts: the whole picture.
Thank you guys for your time and effort helping me understand the science behind this amazing subject!
