Comments by "Paul Frederick" (@1pcfred) on "The Big Misconception About Electricity" video.
If there was no delay then there'd be no such thing as network latency.

That's just the high voltage bridging the resistance of air. You standing on the ground are a path to ground too. Nature abhors an imbalance. So high voltage is just an alien state that needs to be remedied ASAP.

@foxfox-xx3zk you may understand the concepts we think we understand. But be assured we have not completely unraveled the entire mystery yet. We likely never will either. There is a theory that there's only one electron in the entire Universe. It just teleports around everywhere all the time. Now there's a concept to wrap your head around.

@foxfox-xx3zk it is one theory that's no less valid than any other we have at the present.

You can induce a current in a conductor from the magnetic field generated by flowing current. But that current has to change, or your pickup conductor has to move. There has to be some movement between your pickup and the magnetic lines of flux. That's what transformers do. They couple currents. When you apply alternating current to one winding it induces a current in the secondary winding. The two coils are galvanically isolated though. Unless it's an autotransformer. Magnetism obeys the inverse square law though. Field strength drops with the square of the distance. Some overhead wires carry very high voltages so be careful. You might want to watch some videos of high tension wires being discharged. It is sobering stuff.

It's like those balls on string desk toys, a Newton's cradle. You swing one and the other on the other end swings away. Like charges repel and opposites attract. Electricity always wants to seek an equilibrium state. That's why positive charges go to ground. But electrons are actually negatively charged. So conventional current is backwards from what's really going on. We need to make it all as confusing as possible after all.

Offshore wind is a total scam. Years ago some scumbag outfit wanted to stick us with the bill of constructing everything and then they'd own it. We told them to take a hike. Yeah we're going to just give you more than a billion dollars. No we're not!

If electrons don't flow then we can just drop the concept of current.

@voltydequa845 electrons don't flow like water unless they are water. But the hydraulic analogy can still be useful to visualize electricity. Just not all the time. It's how a lot of competent mechanics view electricity and it serves them well enough. So I won't quickly dismiss it myself.
