eli5: How does electricity “know” the shortest path

903 viewsOtherPlanetary Science

I’ve always heard that electricity follows the shortest path – for instance, lightning will use your body for a conduit if you’re the tallest thing around. How exactly does that work?

It doesn’t. Look at videos of lightning. You don’t just see a straight line to the ground, it forks a bit. 
Not a meteorologist but once it finds the way, if lightning strikes multiple times, it would now “know” the shortest path because the air is ionized making it easier for lightning to flow in roughly the same path.
