Ok i have a question about the difference between 240 volts and 120 volts. So from my knowledge power will come from a generator somewhere down the road. it will then make it to my house and a transformer will take it to 120/240. i get 240 120 from each line that are out of phase from each other. and i get 120 from one hot and the middle of the transformer or the neutral. does 120 use the Earth as a reference point of 0 volts to have AC run threw the wires back and forth and 120 volts if it where hooked up to a circuit? and so 240 doesn't use the Earth as a refernce point becuase it uses both phases... so does it just alternate current back and from each phase in your panel or does it go all the way back to the power plant i just don't understand how far the electrons will travel back and forth do they stop at the pannel or travel all the way back the the generator then back again. I am probley way off with most of this if anyone could explain it nice and simple for me that would be great thank you.
And one other question if i have two phases making 240 and i hook up two 100 watt light bulbs in series will they light up and get 120 volts across each of them.. or will this not work becuase they arne't getting the Earth as a nuetral
