In all diagrams i have ever seen of circuits it's implied that electrons travel through load/bulb and bulb makes light/heat.
Now there is a problem here...because of this implied logic i assumed more electrons that follow more power and therefore after power is used in light their speed reduces. But that doesn't make sense what's happening with clogged up electrons.
-coming electron and leaving electron both are the same. I assumed, that unused electron somehow was bigger and puffed and when it gets used its small/slow/ or less charged..But it's none of the above. It's actually the same...So i learned energy is carried via waves that travels through electrons.
Now i don't know what is current or electricity. If used and unused electron both are the same what provided the energy.
please explain how number of electrons, speed of electrons, wave(?) of Energy, and all other stuff fits into how electricity works.
