The Pain of Electricity (AC versus DC)

The Pain of Electricity (AC versus DC)

Hi. One of the common questions is that:
what kind of electricity hurts more? AC (alternating current) or DC (direct current)? So, I’m going to measure the electricity pain level on a human’s body, which is myself. But first, let’s measure the resistance of the skin
on tongue and fingers for reference. So first, let’s measure the V resistance of dry skin. It’s 600K and above. Now, if I wet my fingers with my saliva… you can see it’s 100K and above. If I measure the resistance of my tongue… it’s 10K – 20K and above. So the resistance of the tongue is at least
thirty times less than the dry skin, and it will feel the electricity at much lower levels. And for that reason, I’ll apply electricity to my tongue. I should tell you, I’ve accidentally zapped myself
in the past many times and I kind of know what I’m dealing with. So, you’d better trust me on this one and
don’t hurt yourselves. If you really want to know what electricity pain feels like, then take a 9 V or less battery and put it on your tongue,
and you’ll know. As I mentioned in my other video, a power supply like this one that can generate 70 amps doesn’t necessarily hurt you at all if the voltage
is set very low. Observe… OW! F***! [Multiple censor bleeps] Who the hell set this at 25 V!? Before using a power supply, always make sure
its level is set properly. Let’s try again, and this time, I start from 1 V. I’ll watch for 4 levels: when I start sensing electricity, when it becomes annoying, when it feels like torture, and when I can’t raise it anymore. [Zap] Here we go. I barely feel it at 1V. Uh-huh. Uh. Uhhh… Around 5 V, it’s kind of annoying. Uh… Ah… Yeah, I would say around 9 V, it feels like torture. Although if you want to torture someone and
make them talk, you probably don’t want to hurt their tongue. And besides, you should never torture each other. Always remember, people in the first world countries
never torture anybody, and they always hire a third world country to do the job. Unless, of course, if you’re married. Uh… Ha… Ugh… That’s it. I can’t really go over 12 V. I should say that woman’s pain threshold is
higher than men, so they should be able to go to higher levels. Now, let’s try AC. I’ve heard that human body has some
capacitive properties, meaning that it will let AC through easier than DC. So I expect AC to hurt more at lower levels, and also it will hurt more at higher frequencies. But before that, let me show you something. I’ve set the signal generator to 5 Hz, 7 V RMS. Let me change the frequency now. Nice. By the way, I can do this too. Now, let’s reduce the voltage level and increase
the frequency all the way to 60 Hz. [Loud pop] [Multiple censor bleeps] I shocked my ass sitting on these live wires. Always clean up a lab, otherwise something
will bite you in *** [Zap] [Multiple censor bleeps] Okay, AC is starting at 1 V. Hmm. I can definitely feel it now. Uh. It’s quite annoying at 3.5 V. Oh… It’s torturing at 4.5 V. Oh– Ah– That’s it. I can’t really go over 6.5 V. So it was confirmed. According to my sensors, the AC hurts at RMS levels half of the DC level. Anything for science. ♬ Shake it, shake it, shake it, shake it ♬

  1. My older brother is an eletrical engineer, i guess he's so proud of you, as a professional stupid electrical engineer.

  2. Я тоже как-то крону лизнул, это далеко не из приятных ощущений.

  3. LOL are you insane? why did you do this to yourself? many times ago , i tasted 300 volt. and it was not tasty. actually it was painful. a few times after when I shocked by electric city again. i started to have fun 😀

  4. I was once fiddling around with a plug I couldn’t get into the outlet port. I keep struggling with it for a while and somehow, my fingers get so close to the prongs of the plug and the port, and I feel something move from my finger, through my arm, and end in my chest.

    Imagine a snake slithering through your body while vibrating…

    And no, it didn’t hurt me. It just felt weird having that feeling..
