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

[-] Melkath@kbin.social 79 points 2 years ago

You don't shock the person.

You heat up the metal until it burns them.

[-] 0ops@lemm.ee 16 points 2 years ago

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

[-] toxic_cloud@lemmy.world 34 points 2 years ago

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

[-] TrickDacy@lemmy.world 25 points 2 years ago

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

[-] SaltyIceteaMaker@lemmy.ml 13 points 2 years ago

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.

[-] captainlezbian@lemmy.world 7 points 2 years ago

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

[-] mingistech@lemmy.world 9 points 2 years ago

No, 9v batteries have almost no shock to them. Put one on your tongue or lick your finger and touch the terminals. You’ll feel nothing.

[-] rotopenguin@infosec.pub 39 points 2 years ago

Dry skin is hundreds of thousands of ohms. Even wet skin has pretty good resistance. When you touch a 9v to your tongue, you're starting to mess around with lower resistance flesh, it is definitely not a comfortable thing to do.

The metal ring doesn't do anything to move more electricity into your body, but it soaks every electron the battery can push and turns it into heat. Best I can figure it would amount to a few watts, which would be toasty if you were holding it between your fingers. The septum is a thin piece of flesh, I think it would sauté pretty quickly.

[-] Lauchs@lemmy.world 11 points 2 years ago

Thank you, I appreciate the explanation. Being fairly physics ignorant I was wondering about that.

[-] Gandarf@startrek.website 30 points 2 years ago

I mean, if you lick a 9v you definitely feel something. It's not painful, but it's not natural or pleasant either.

[-] Swarfega@lemm.ee 6 points 2 years ago

Can confirm. Used to lick them as a kid

[-] ChaoticNeutralCzech@feddit.de 3 points 2 years ago

If those are separate pieces of metal embedded in the skin, they will feel something. If it’s just an incomplete ring, it will draw so much current that the battery voltage drops too low to feel anything but the heat.

[-] TrickDacy@lemmy.world 17 points 2 years ago

Another confidently incorrect person

[-] shani66@lemmy.comfysnug.space 3 points 2 years ago

What? They are clearly just screwing around man.

[-] SpaceCadet@feddit.nl 3 points 2 years ago
[-] CodyCannoli@lemmy.world 7 points 2 years ago* (last edited 2 years ago)

But it'd probably get really hot

[-] Hikermick@lemmy.world 6 points 2 years ago

Just put a 9volt in your pocket with some change
