Would it be ok to use your video as part of a training course I am putting together? I will reference the company and the address of the video as part of the training.
how about static from slides because my friends and i play around with it and we slide on the slides and touch each other a get shocked but it doesn't hurt much it just surprises us
I know the animation would be better showing the electrons instead but Its just a referencial. Like in mechanics when u consider a moving thing as static and everything else is moving, or electric current, which the standard current direction consider that the protons are moving. It works for everything if done properly. Also positive charges as positive ions do actually move because of electric forces. This is called ionic current. In fluids they move a lot, and they can go from one solid object to another(like air or tiny drops of liquids). And they also move throught solids like dust, hairs or sand which can and do move from one object to another. Electrostatic precipitators works with these concepts.
The triboelectric series is a list that ranks various materials according to their tendency to gain or lose electrons. It usually lists materials in order of decreasing tendency to charge positively (lose electrons), and increasing tendency to charge negatively (gain electrons). Somewhere in the middle of the list are materials that do not show strong tendency to behave either way. Note that the tendency of a material to become positive or negative after triboelectric charging has nothing to do with the level of conductivity (or ability to discharge) of the material.
Hi How does touching the metal case of the computer help to discharge the body of electric charge if the computer is unplugged? My view was that you can only discharge the body if connected to an earthed/grounded cable?
Charge will only dissipate fully if the metal computer case is earthed. If the computer is unplugged and the case is not earthed, there will be a sharing of charge determined by the relative capacitance of the case and the body. The body and the case will not be at zero potential, but the potential will be the same on both the body and the case. This is a form of equipotential bonding and will minimise the risk of any damaging sparks occurring, for example when installing sound cards, etc
hi. Can you please explain what you mean by '...if the metal computer case is earthed'? I have seen many videos were people state that you must touch the computer case but not a explanation as to how this method works.
The computer is earthed when it is plugged in the wall or when it is in contact with the earth (e.g. when is placed on a metal table). You will discharge yourself when touching the metal computer case.
It really depends on what is going to set off a spark: you (static electricity), or the installation you are working with (current electricity). If you are working on an electric installation or system, you need to wear insulating gear (i.e. by wearing rubber gloves or boots). However, if you want to prevent build-up of static electricity on your body when working in an explosive environment, or working with delicate electronics, you need to wear antistatic gear and you need to be grounded at all times.
Static charge can be drained with very high resistance, well in excess of what would support enough current to shock you from 120 or 240Vac. I work on electronics for a living and as a hobby. Antistatic wrist and heel straps must include a 1M ohm resistor between your wrist and ground. Work mats have a resistance per square between 1M and 10G ohms per square. If you are working with electricity at a dangerous voltage, it is a bad idea to be directly touching ground. At 240Vac wearing an ESD wrist strap with 1M ohm resistor and assuming worst case you puncture the skin, 240V/1M = 240uA. We can take into account that it is AC and so the peak is about 340uA. I tested myself and found that the most sensitive place on my hands was the skin between two fingers. The threshold of sensation was 300uA, and I could barely feel it. I had expected fingertips to be most sensitive, but I think the thicker skin spreads the current to a lower density before it reaches the nerves. Over the rest of my arms, it took about 1mA to just begin feeling it. It is amazing how quickly it becomes excruciating, only 5mA was very unpleasant when the contact area was confined to a blunt probe tip.
I have managed to paralyze someone's hand for five minutes cause I was wearing a sweater and I handed over a basketball. I've also had an incident it two with glowing palms against a blanket, and I can pretty much move tiny objects without touching them at any given time. My mom takes the prize though. She managed to crash a computer just by being in the same room, turn on the TV by walking next to it TWICE, and TURN ON A PC FROM 2 METERS DISTANCE. It's NOT cool. We can't go a day without electrocuting someone or ourselves!
i thought paul died in the last clip, what is he doing walking over to a production area? or did he just get hurt really bad? lol sorry i know not funny wait, youre making me laugh, so it's YOUR fault! ok now i can guiltlessly say lol
Hello FAM, thank you for the very insightful video. My classmates and I very much appreciate it, tank you very much :0
same with this young kind man you provided very helpful and useful information for me and my long lost friends. hooray big bollocks
Um why doesn’t Paul know what static electricity is it’s basically his job smh
Shouldn't the charges be drawn as negatives rather than positive "plus" symbols?
Is it just me or does the guy sound like markiplier?
Yeah😂
That's his side job a physics teacher

4 yrs later.. no reply.
I'm just glad Paul is a cartoon character. xD Industrial Accidents are NOT FUNNY. lol poor Paul.

its not dangerous they are perfectly harmless!
The protons ( the positive charges ) never move! Only the electrons are transferred from objet to the other.

Safety shoes and smocks helpful too
poor paul. google the triboelectric series if you really need to know which gets the electrons
😀very nice video
Can I ask you what is the meaning of negative voltage? What is the difference from positive voltage in terms of work and energy?
The triboelectric series is a list that ranks various materials according to their tendency to gain or lose electrons. It usually lists materials in order of decreasing tendency to charge positively (lose electrons), and increasing tendency to charge negatively (gain electrons). Somewhere in the middle of the list are materials that do not show strong tendency to behave either way.

thank you Ijust wanna know what app do u use

But what happens if you're working with electricity? Should grounding or touching the ground be a bad idea?

nice
Creative
I hear Batman over and over, for some stupid reason.
No one cares🙂
Yeah no one cares
I thought only electrons can transfer from one material to another???
Now I get it, why would a person ignite their vehicle at pump station.
Electrons are negatively charged ... Paul would be in really bad shape if protons were passing through him like that....

rip paul amiright
pog
I m like Paul 😑
f
wrong narrator voice, and the guy should be named Timmy
lol
i thought paul died in the last clip, what is he doing walking over to a production area? or did he just get hurt really bad? lol sorry i know not funny wait, youre making me laugh, so it's YOUR fault! ok now i can guiltlessly say lol
In my opinion, it's weird lol :)
