voltage rule

You'll have that when your voltage overcomes the resistance of the air
- Sometimes it happens even below the arc breakdown voltage via air... Air molecules are slightly less dense along the surface of a smooth flat surface due to molecular 'bounce', so electrons creep along the lower density of a surface.
  Hence, creepage on a PCB.

High frequency signals be like: conductors? Where we are going we don't need conductors!
- What's the center of this copper wire even for, anyway? I'm going around the edges.
  
  True that. I was amazed how many hundreds of amps I could dump into an aluminum foil antenna at high frequency.
  Just aluminum foil around PVC is practically as good as solid aluminum pipe.

Why is high voltage that hard to read?
- zalgo used to represent the demonization of high voltage
- it's also a reference to an existing meme
- Because it follows every path at the same time

Silicon isn't a conductor, it's a semiconductor. Also conductivity is dependent on temperature, hot stuff usually conducts easier, though some things conduct easier when they are colder. Even at the low voltage it's more complicated than "Conductors" and "Insulators" we learn in those ultra basic electronics guides online (or in school if you're lucky).
- Hot stuff always conducts. As in plasma.
  
  Except superconductors often conduct better when they are cold (unfortunately, would be nice if a room temperature one was found but probably isn't going to happen).

Thank you for this powerful visual. I've always had trouble understanding electrical concepts, but this is beginning to open my eyes now.

If electricity is a highway, current is the number of cars at any given time, voltage is how fast they are going, and high voltage are the driving sequences from The Transporter / Fast & Furious movies.
