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.
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.
Thank you, I appreciate the explanation. Being fairly physics ignorant I was wondering about that.
I mean, if you lick a 9v you definitely feel something. It's not painful, but it's not natural or pleasant either.
Can confirm. Used to lick them as a kid
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.
I like that feeling
Another confidently incorrect person
Woosh I guess
But it'd probably get really hot
