Here is an example of two 120 lines coming together to make 240v. It would appear to me that this shouldn't work at all.
[picture omitted]
How does the two voltages add up? Why can we tap into one 120v line and into another and get voltage across this wire? Especially all the voltage added up together.
The power transducer you are looking at is for a 3-wire split-phase system.I will try to use this in another way. Sorry for the confusion. I am confused but I will try looking at it another way.
Lets look at it as the difference of potential. The difference in potential of the DC 12v versus the 5v is the 7v because one side has more electrons(is pushing more electrons) than the other. I guess making the lesser voltage side the positive side. The difference in potential in this case would be that the 12v side is the more negative side and forces its will that it needs to get rid of electrons more so than the 5v side. The difference is in that the 5v side becomes 0 and that the 12v side is different by 7v.
Where is this difference in potential in the AC circuit pictured? Being the same phase, I would think then that the difference in potential from 120v to itself would be zero.
Maybe this description will show the flaws in my understanding. Hopefully you can use this to correct my thinking. Of course, that's if I am even in the ballpark of knowing whether that's an accurate analysis of what's happening.
Thanks so much in advance!
