Hello /sci/
I recently watched this video:
https://youtu.be/bHIhgxav9LY
and I realized that my understanding of electricity is that of a kindergarten pigeon - I was hoping someone on /sci/ knew a lot about electricity and could make me less retarded
Please forgive me for the misconceptions and stupid questions I will ask in this thread
>At 8:00 timestamp, they show the magnetic field going from the battery to the bulb, and say that the lightbulb is getting energy from the field
>at 12:15 timestamp, he explains that the electromagnetic field crosses the 1 meter gap to the light bulb
so.. I understand that there is some disagreement on the light bulb lighting in this way, I read one argument that said that the bulb would light up in the 1/c timeframe for a millisecond from the electromagnetic field, and then go out, and then after 1 second the current will close the circuit and it'll turn on
I guess I just do not understand how the electromagnetic field bridges the gap between the battery and the light bulb, and how the field is what powers the light bulb, not the current
I know that to you this seems like a basic question - but I really don't get it
I don't understand how this applies to all transmission of electricity
eg. power lines - does the magnetic field extend from the power station to your home - "bridging the gap" in the same way that the field goes from the battery to the light, or does it only create the magnetic field around the wire itself? (or both)
How does the electromagnetic field make the lightbulb turn on?
I always thought that (in old light bulbs) the current would heat up the filament to where it would glow
Does the electromagnetic field heat up the filament?
I don't understand the role of electrons in all of this - I've read the analogy that the wire is like a pipe filled with ping pong balls, and when you push one ping pong ball in another one comes out - is the speed/force at which ping pong balls come out the voltage?
