about a year ago i have asked how light bulbs work, the tungsten one. i was satisfied with the answer but not anymore. In brief (to make sure I have a proper understanding): as the electron moves from the higher to the lower end of wire in terms of electric potential, it releases energy. The energy is absorbed by the electrons in the atoms of the wire. The electrons jump when gaining energy and, being unstable, fall back to the original orbit, releasing photon in the process. My question is now, simply, are the electrons in the power source energized as they have a high volt? volt itself is described as energy/charge. Thus I interpreted the energy to be inform of photon and thus there would be either abundant amout of photon around the electrons in the power source, or just the same number of photons with higher frequency or both or am I simply wrong? Then, is the electical energy and the light is both in the form of photon? Thanks in advance.
