Where Does Grounded Electricity Actually Go?

[Retro]

We tend to take that ground wire in our domestic electricity supply for granted, but why is it really there, what does it actually connect to and what happens if you remove it? Practical Engineering explains all this and more.

Bonus: this video has pictures of unusual electricity pylons for special cases that you may not have seen before for the very fullest nerd experience.

Saved to 'Watch Later' as I do find this fascinating. Electricity travels at 186,000 miles per second, same as light (To the best of my knowledge), does resistance affect the speed or merely a power drop at the end of the circuit?

Nice topic....watched a few minutes and I'll have to come back another time. I do like the quality of how the information is taught so far.

Interesting video, must admit most of it was totally beyond my understanding.

Achievement unlocked!

If I'm honest, I don't always understand everything either in these videos.
