High Voltage AC/DC Effect on Human Body

hi I have a video on the pain of electricity but now I want to kick it up a notch and show you at what voltage it hurts over skin rather than tongue I'll be trying 120 volt AC 170 volt DC and 340 volt DC but I don't have a high voltage supply so I'll put together my simple circuit the circuit looks like this just two capacitors and two diodes at this point I applied 120 volt AC and across c1 I will have 170 volt DC and across c2 i'll have 340 volt DC please check my website below if you like more detailed explanation as you see the voltage levels on this circuit are very dangerously high you might use this circuit for low voltage applications but don't use it as I do or it might be your last day on earth I make a simple circuit and I'll plug it in now that circuit is hot and the voltages are this something you must never forget is that some capacitors like electrolytic ones are polarized and you must never connect them backwards or they will blow up now I have replaced the capacitor on my circuit and I'll plug it in in addition to polarity the capacitors must be rated properly to be able to handle the voltage across them or that you'll blow up obviously I picked 150 micro farad 400 volt capacitors as the maximum voltage these capacitors will be charged to is 340 volt DC now there is nothing to worry about like I said everything is good there are three voltages on my circuit the first one here is the 120 volt AC which is very dangerous I've accidentally touch 120 volt and 220 volt AC and they hurt a lot and can kill so I'm not gonna repeat that again this one here is across the first capacitor which should be 170 volt DC and that one there is across the second capacitor which should be 340 volt DC let me measure them for you to measure the hunger 20 volt AC I put the meter on AC and I measure the voltage god sometimes when you're probing a line you might touch the probes but never forget about the voltage on the probes here I have 120-volt AC on the input and if I change the mirror to DC you'll see that there is almost no DC on the input what if I measure across the first capacitor here you will see that there is around 170 volt DC which is equal to the peak of the AC signal as expected this is a much higher voltage and can provide much more power now let me touch this voltage hmm I can barely feel anything although I feel a little bit of tinkle on my skin but remember if my skin is more conductive for any reason it can hurt much more I have two light bulbs here that both are 60 watts i connect one of them to the 120 volt AC input and the other one to the 107 volt and you see that the one on the hundred 70 volt DC runs much brighter and I can barely feel that one on my finger I can't even hold the ball to the hundred 70 volt DC with my fingers now let's try the last capacitor you see there is 334 volts on this one let's touch this one ouch ouch well this one hurts much more but not nearly as bad as the 120 volt AC now let's do the light bulb test you see the ball one the 340 volt DC runs much brighter than the one on the AC and yet it doesn't hurt even close to the AC the reason is that the human body has a capacitive property that allows the AC signals to run through much easier and therefore there will be much higher AC current that can hurt or kill a person while the DC signal is greatly blocked by the resistance of the human body if you are curious to know how a capacitor behaves here is a symbol of a capacitor and these are its plates when there is a DC signal like this it hits the capacitor plates like this and gets blocked while an AC signal can zigzag between the plates like this and pass through

2 giant capacitors, 6 exposed wires, all wired into the wall socket.

Safe!

Hey Melector, you are the funniest guy I have ever seen doing this stuff. I actually have a huge fear of electronics, but, still I solder stuff together and play with dorky circuits. You have pretty much made all of my fears seem childish. I am glad I won't die making mistakes. I don't fear electricity nearly as much as I used to thanks to you. You are my electronics hero.

God, that guy's professional :-D

Love this guy!

I thought he meant this High Voltage AC/DC effect :< Rock on in Heaven (or Hell) Bon.

I remember you said you were working on a big project for a video, how's that going?

So, Edison was kinda right when he claimed that Tesla's AC would be more dangerous to work with? He definitely was a dick about it. Poor Topsy.

Not sure if brave or stupid.Either way, fuck that for Sunday afternoon entertainment!!

Hi I work in power production for the air force and I loved this video. Do you have more videos like this explaining things? I'm thinking about using them for training in my shop.
