i know this is a silly question, but i couldn't manage to wrap my head around it. I am kinda new to electronics.
My home's outlets provide 220V. Upon doing some (a lot) research, the current that this voltage can supply is enough to kill me. However, when i try to do the maths myself, i can't seem to get the correct answer.
according to google, the current needed to kill a person is between 0.1 and 0.2 amps and the human body has a resistance of 100,000 ohms.
Say one day i decide that i don't want to live anymore and put both my fingers inside the outlet completing the circuit.
So, considering the formula V=I*R,
220 = I * 100,000 -> I = 0.0022A
which is way less than 0.1A that is needed to kill a person. I know that i am doing something wrong here, but i just couldn't figure it out. Some help would be really appreciated.
 this question was just to ask if my maths is correct. I am trying to build a toy stun gun (harmless stun gun?) But, i wouldnt want to just find out if i got the voltage right by testing it on myself. So i figured if my maths is correct, i can calculate how dangerous my toy stun gun will be (i can not find something like that on the market where i live) do you have any advice? Or is it just too dangerous for me to even try?
[edit 2] Thanks to everyone for answering my question. I have come to conclusion that stun guns are way more dangerous than i first assumed and not something i should mess around with. gotta find another project, i guess~
