Teen saves his friend from electric shock

A ground, typically another piece of metal, or water, or just ground with sufficient metal elements in it.

Since the human body has some non-metallic elements in it, it also contains resistance, which increases the current.
How do I know?
I have permanent burn scars at my left elbow and wrist where I inadvertantly hit a CRT power circuit and the side of a metal radar display console -and got stuck until I could kick myself free. Thing is, I didn't feel the burning. Just frozen, and panic from the realization that I was stuck.

The release threw me 15 ft. back against a file cabinet, butt first.
Couldn't move my left arm for a week, it took almost a year to recover. Now I have severe arthritis in that arm, so I never really recovered.
