I skipped physics and chemistry for language, I knew about jumper cables, that’s it. The diagrams in the pdfs is what helped me understand it: all electricity wants to go to the earth, like lightning bolts. Unless you are in the path of it’s way to the earth, it won’t affect you. That’s why birds on an electric wire don’t get zapped, there’s no connection to ground. So when you send positive electricity out along a fence wire, it has no way back to ground and zapping anyone until someone with a connection to ground touches it.
You can still run your fence, you’re just limited as to where you can put your ground.
This! Yes the Circle Of Zap made sense with diagrams like this!
I forgot about the Posi-Neg fences. They create their own complete circle and so when a critter touches both wires they become part of the circuit and get a zap. This is more like the home wiring - both parts are right there. Like putting a knife into an electric outlet - yes we did that as kids for a brief spell, what idiots! - you’re holding the steel knife (very conductive) and you’re hands are conductive, so you’re part of the compete circuit.
