How do you know what to touch, and what'll murder you? Whenever you touch a thing, I get a twinge of fright. 😂

Pumpkin he would cirtainly be crisped if he had the ignorance of electroboom

[@StofStuiver]

Its been a year, but ill try answer it: First off, you may want to not touch things far before it kills you. You did provide a neat line in the sand though, but its still not cut and dry who dies and who doesnt. So: 1) Generally, most damage is done to tissue by heat. Except for the criterium you put up; death. That one is most common from AC, that pulses the heart out of rythm, rendering it non functional and possible unable to reboot after the outside electric force is removed. Same applies to nerves/brain, up to an extent. So apart from those, it is heat, resulting from a current running through us, with a minor resistance. And that will eventually, depending on how much it is and where it is, burn our cells = celldeath. And on top of celldeath, we get all sorts of systemic reactions which may also kill you. 2) In order for a current to run through us, the Voltage needs to high enough to overcome the blocking resistance we have. If resistance is too high, there will be no current = no heat = no burning. If the resistance is 0 (theoretically), a huge current may run through, but it will not create heat = no burning. Thats also why you can see him melt spanners, steel rods, etc, that are thicker than the copper cables connecting to it. So why doesnt the copper melt? Its melting point is lower than that of steel. Its because copper is a better conductor (has a lower resistance), than steel. So provided a voltage is connected to us that overcomes our resistance, a current will flow and the region the current flows through us, will heat up. 3) But we are not consistent in composition. Even though people are anatomically 'equal', our body chemistry may differ quite some. And it will also vary in a person depending on conditions over time. So the current may run through muscle, or through vains, or along nerves, etc, depending on their conductivity at that time. And if we apply the electrodes to our skin, a huge differnece there already is if we are wet or not, or even better; sweating. Sweat contains a lot of salts, in a water solution. And that is a great conductor, while the skin itself (~dry) is more of an isolator. So when your skin is very dry, a current may not run at all, while when you are sweaty, it may run easily. Suppose we overcome both by a high enough current: In a sweaty person, the current will run over the skin; through the sweat. That will heat up and may steam off even. That initial heat will burn from the outside in. A person with a dry skin; the current will run under the skin somewhere. The heat will originate there and burn you there. From the inside out. 4) Generally; voltages up to ~40 V will not allow much current to flow, if at all. (depending on how dry/wet/sweaty your skin is. Anything above that will penetrate through the skin and a current will flow. But it may not cause any harm at all, because it also depends on how much current is allowed to flow. After all; P=U*I (Power = voltage * current). So you may grab 10 KV, but if the current allowed to flow is limited to 0,1mA, it is not going to burn you anywhere in the near future. It will heat up so little, out body is able to get rid of the generated heat easily. 5) Another thing to keep in mind is that you may touch an open mains wire and nothing will happen. After all, no current will flow if there is no closed circuit. You may be wearing rubber soled shoes. Standing on a rubber matt, or anything such, which prevents a current to flow. It is how birds can sit on high voltage wires and nothing happens. Well, as long as they dont touch the other wire that closes the circuit through them, no current can flow. If they do, it tastes just like fried chicken i guess. 6) Examples: A young guy is laying opposite my mom at the graveyard. He was biking with his GF here, 28 years ago, over a dike and lightning struck. He died instantly. Other people were struck and they had no damage at all. Others had skinburns. (it all depends how much, where, wet/dry, etc) You may hold batteries with no problem. Ever put a 9v on your tongue? Try it. Tongue is wet and saliva full of salts and sugars and so; conducting very well. There is a reason welding devices are limited at ~40 to 50 V. After that the voltage would become dangerous for welders to work with. So it is not so easy to answer what is dangerous and what is not. It depends on a number of factors, which i tried to explain. I hope it clears it up a bit. Seeing what our dude here does in his videos, it seems to me he knows very well what he is doing. But i understand to a lot of people it must seem like magic. (also because of the many comments on how the grid would suffer from what he does, when in fact, a lot of the things he does are not that high in power consumption. It just seems so, bc he shows things you often dont see in electrics and look impressive. He is also limited to what the cables that run into his house can carry. And the main fuse box. Ofc he circumvents it somewhat, with HUGE capacitors, which store an amount of energy, similar to batteries, but able to release that all in a millisecond. Those are charged from the mains. You cant just take 100 amps @ 240V from the mains. But you can load capacitors and then use that for a short time)

I have an old arch welder that my grandfather made. It would weigh at least 50Kg (110lb), it's really really old in a wooden box with material insulated wiring. It would be a fair bit more than 200amps I would assume, it has no trouble blowing holes in 10mm thick plate. I have to run it on 15amp mains @ 240v, it blows a 10amp fuse real easy.

Hi ... Did you have this plugged straight into three-pin wall socket (240 volts (13amps)) ... !? I see you have run your ''input'' electrics through a couple of things. Does one of these oil cooled welders pull more and more from the input electrics, or can you just run them up, and they will create whatever they need on the out put side! I have one; but not sure if I can run it from the house electrics ... !? Thankyou. Interesting vid. Best ... William (Hampshire UK)

[@saabinsanity]

hi there you need to be very careful my friend doing this !!! I have seen those copper coils unwind and cut through the metal casing of the machine ! The copper goes hard in places usually back from the soldered joints on the choke and where the clips bolt on to the paxoline selector arc and flash across so check the tightness as well as the copper braided connection stay safe and make more vids mate

[@nerdysophie]

That is why the copper can handle UHV+ (Ultra-High Voltage and up), or 57,009,864 Volts. My friend, these copper wires should be used to replace HV (High Voltage) wires for transmission, even in short-circuit, or sudden voltage overloading, conditions. People who select the proper line material should know that and select it.

Dude, I love your videos but I have questions - in lay-men's terms, what's the difference between lots of amps at no volts and lots of volts with no amps? What are examples of real-world uses for each? Thanks for sharing your knowledge with all of us!

[@johncoops6897]

2 years later, I will offer a reply... First the answer to your question. The ultimate answer is nothing, because both are zero. However, that's also not the ful answer because Volts and Amps are two different things. They only become useful when both are used together. If one is zero, then the other is useless. Only when both Volts and Amps have a non-zero value, then Watts (power) can exist. . Voltage is the difference between 2 points, where potentially some electricity could/might flow. Current (Amps) is the *amount* of any electricity that is actually flowing (due to voltage). . Often an analogy of water is used... this is not a perfect model, but let's consider a huge lake, with a dam blocking it from flowing into a river below.... . 1. The *height* of the Dam is the potential difference (Voltage) between the dam and the river. 2. The dam itself is the Resistance (Ohms) to that water being able to flow from dam to river. 3. The *amount* of water that is flowing to the river is like the Amps. . If the water is completely blocked by the dam (infinite resistance) then no water will get into the river. It doesn't matter how low or high the lake is, the water cannot flow. - This is like having a High Voltage against a high (total) resistance that stops it, so the Current will be zero. . If the lake and the river are the same height, there is no potential for water to flow. It won't flow down into the river because there is nothing to push it. - So this is like having Zero Voltage, because there is no potential difference. No current (Amps) will flow, and the resistance of any dam doesn't matter. . If there is a height difference and then dam is suddenly removed, all the water will flow between the lake and river until they are the same height. While that water is flowing, it's a current. - So if there is a Voltage and if Resistance is low, the electricity with flow at a "rate of" Amps until all the Voltage is gone. . OK, now let's make a hole at the bottom of the dam, allowing some water to come out. We have will a flow that depends on two things... the height of the lake water (Volts) and the size of the hole (Resistance)... . The bigger the hole, the more water can flow through it. The lower the resistance (Ohms), the more water can flow (Amps) for a given potential difference (Volts). . However, the amount of water that actually flows through the hole also depends on the pressure, which is the height difference between the lake and the river. - So for a certain resistance, the current (Amps) is ALSO dependant on Voltage. . Therefore: the Volts, Amps and Ohms are all 100% completely dependant on each other using the formulas: Volts = Amps X Ohms Ohms = Volts ÷ Amps Amps = Volts ÷ Ohms . Summary Without Voltage, Current cannot flow. The higher the Voltage, the easier it can overcome a Resistance. So, whilst air has a high Resistance, a very high Voltage can jump across (arc) and cause a Current to flow. The resultant spark might not contain much Current (eg: Static Electricity) but can also be huge (eg: lightning).
