Would the person feel anything? Presumably the electricity would flow through the metal as path of least resistance?

You don't shock the person.

You heat up the metal until it burns them.

I used to burn paper with a 9 volt and a paperclip. Good times

It's a short, the metal would heat up extremely fast and burn.

[–] [email protected] 25 points 10 months ago

Yes, it would heat up. It would not be pleasant

They prob wouldn't get shocked but the ring and battery will get very hot very quick as there i pretty much no resistance wich means there is a lot of current flowing.

Someone else in the comments claimed to have calculated a resistance of 0.2 ohms.

I=U÷R

9V ÷ 0.2Ω = 45A

45 amps is a lot of current to flow through a nose ring. I don't know how much that is in heat but i'd expect you to get burned from it

You won't get more than a few mA out of an alkaline, but heat does build up. (Internal resistance)

A NiMH on the other and can give over 10 amps. They're a seriously risky thing to leave around loose metal bits. Or attached to thin wires.

Definitely won’t get shocked. I’ve run estim through nipple piercings and no shocks

Just put a 9volt in your pocket with some change
