what happens when you lick a 9-volt battery?

zap

Nothing would happen. Why should anything happen?

If you are thinking about the danger.. I may calculate it for you..

10 mA (current) is reported to be dangerous for human heart.

If you use a voltmeter and send current through your fingers you will find that we got around 50k - 1 M-Ohm.

Volt / Resistance = Current

9 V / 50 k-Ohm = 0,18 mA

0,18 mA would be out of the range we would consider dangerous to human. But if you lick the battery, the current wouldn't flow through your heart and disturbe your heart rhytm so it would be non-dangerous.

purely get zapped is all, not something particular. attempt licking a wall outlet in line with risk that'll provide you the fee you require, touching products then might wade by means of your physique into surrounding gadgets

You get a quick shock and you end up with a funny taste in your mouth. Nothing harmful, just kind of dumb to do.

I have heard it tingles a little. I haven't done it in a very long time.

Your tongue gets a little zing/zap...There are many other uses for this type of sensation as well...Eroticism for one.

It tastes kinda funky. But you won't drop stone dead or anything.

Try it out and tell me the result.

i wouldnt do it :)
