[ELI5] Why is the difference in potential of electricity the one that kills you?

672 views

I found something on reddit about this. Basically it goes like this:

If there is a broken live electrical post falling down on your vicinity, you need to hop up and keep your feet close together instead of walking.

The explanation for this is that if your feet are far apart, there’s a difference in potential between your feet. How does this work?

I really don’t understand what the internet says and maybe someone could get me the answer if it’s eli5’ed to me. Thanks reddit!

You’re probably thinking of something like this video where it recommends shuffling https://youtube.com/watch?v=fLVzvMTgGDY (I included a video from a reputable source because I don’t want to risk giving bad information on something life or death)

What happens is that electricity wants to find the easiest way to go from one location to another. if you spread your legs then you might conduct better than the ground that you are crossing. Because it’s easier to go through you, a flexible bag of mostly water , than it is to go through that dry ground. if you have very short steps then it is easier for the electricity to flow across the ground than it is to go through you
