Hi so I am wondering about potential phase difference in some 110v 60 hz household wiring... Say I have two switches to control one light and am too cheap to buy 3 way switches. If I were to run power from switch 1 to switch 2 (bypassing switch 1), so that they both had power at the switch, if I were to turn both switches on, would the difference in phase at the light cause a problem? (granted at such small distances it will be a small fraction of a degree out of phase)
From a theory standpoint, if the voltage propagates at .5c, then .5c/60hz = 2,500,000 m, so for 90 deg out of phase we would need 625,000 m of cable... think of a single long wire which is hot loops around and touches itself, from the point of contact to the end of the wire is 625,000 m (90 deg out). While it is touching what is going on in the wire? lots of current? superposition? something bad? lol
Lets go a step further and make it 180 out of phase... what then? no voltage on the line? what's the current doing? does my generator explode? XD
thanks
BTW i am NOT actually going to wire my house like that, just curious
