Okay, now I need to read a sci-fi book where someone gets on this weird sci-fi planet, and maybe at the middle or end we find out that those are aliens and the planet is Earth. Sounds like a great premise and I’m sure such book was written. Please, someone tell me in the comments, I need to know.

Under high voltage the current still follows the path of least resistance even when it looks like it does not. What people don’t think about is that resistance is not a constant and under strong enough electric field dielectric materials (isolators if you will) can loose their propeties. Strong enough field can rip electrons from elements causing ionisation. Other things such as temperature, mechanical stress, radiation also affect different materials.

So what high voltage changes is making it harder to resist, but charge will still follow least resistance and aim to go for the nearest lest resistance material if such is available.

PS: I have studied all of this in a different language so I may have mixed up some of the terminology in English

I wish I could do that and save so many electrical engineering student the confusion

Yes, except if you are in my University, where professors are fossils and knowing OSI is required to pass the CN exam.
