Where does energy come from?
If a light bulb is connected to a generator 186,000 miles away, it will take one second before the bulb lights up. (Hint: speed of light) But, electrons, the supposed carrier of current and energy, only move 23 micro-meters per second.
So, where does the energy come from that lights the bulb? The electrons only moved 23 micro-meters. So how did the energy get into the light bulb?
Should we redefine current flow? Can this be answered without dragging Mr. Poynting into the discussion?
Thanks for your consideration,
