Think of the way electricity “flows” through a conduit. That conduit, often a copper wire, is one available pathway for this mysterious force to explore. One way to think of it is flowing. That has been the accepted and agreed upon concept of how to describe this mysterious force. Another equally valid way is resonance and motion.
Imagine trillions and trillions of copper atoms hanging around, nothing to do, locked in their prison cells of an encapsulating insulator. Electricity knocks on the door, and one copper atom answers. The nucleus of that copper atom is excited, and begins to dance. That dance induces all of its neighbors into near instant action. Like “the wave” moving through a sports stadium, a resonance is passed along, at the speed of light. Perhaps the electricity that we thought was flowing was really just a way to incite one single atom into action, which then had the domino effect of the inevitable crowd uniting.
This dance of the copper atom is precession. Like the earth wobbling on its axis, the copper atom’s particular motion of precession enables it to celebrate its message in a way that many other elements are unable to.
This celebrated message is, of course, vibration. This vibration is passed along to all the adjoining neighbors in a most efficient manner. The original message at one end of the circuit contains details about voltage, wattage, current, etc. The message is held intact as long as possible. The further this message has to travel, the more it degrades. The reason silver is a superior conductor of electricity (as compared to copper) is because unlike copper atoms, silver atoms precess in unison. They are more crystalized, acting as one unit; the message is delivered with more efficiency.
The reason a filament type light bulb “lights up” is because the material and amount of matter in the conduit changed. This force of vibration that is “flowing” through a wire, passed from one copper atom to another, suddenly encounters something else.
