I'm interested in how static electricity is managed in vehicles. I remember...
In a post I made in the materials engineering sub forum someone mentioned the field extends only a few atomic spacings beyond the surface of a crystal, in the case where I was thinking a micro crystal grain.
After talking to a physics lecturer he mentioned that due to the positive and...
