Lightening is DC power. Current flows one direction in a lightening strike. Tesla used high frequency in his coils because he wanted to transmit power over long distances. He wasn't trying to produce lightening! The discharge into the air was a side effect which he didn't like. You can produce the same voltages by hooking a transformer up to an outlet in your house. However, as you increase the voltage your current will decrease.
Current limiting works in two ways. One, you lower the voltage to get the desired current. Two, you turn the power supply on and off a certain percentage of time. So if the current will reach 500 amps at 100 volts you only power it up 1/5 of a duration of time to achieve an average current of 100 amps. This is a PWM circuit and it still wouldn't be the effect you desired.
Fun related fact: The Calutrons used in the Manhattan Project harnessed ludicrous, insane strength electromagnetic fields to separate Uranium 235 from U-238 in a gaseous state. During wartime, copper was in short supply, and finding thousands of TONS of it to construct these electromagnets was impossible...but was possible was the massive stockpile of SILVER held by the US Treasury. By the end of WW2, 14,700 short tons of pure silver were used in those probably quite beautiful electromagnets, at the time worth over $1 billion in 1940s cash. If it came down to having to have that coil, with that secondary, and we were motivated enough, a quarter million per coil is incidental.
So bottom line, playing with Tesla coils can be fun and give dramatic displays. People often charge themselves up with them and shoot sparks from their finger tips. However, all it takes is one mistake. They become the path from the secondary coil to ground!
I work on medium voltage equipment. Medium voltage accounts for AC circuits 1000 to 35000 volts. A recent circuit I worked on was 4160 Volts rated for 4000 amps continuous. Now lets think about what would happen if I grabbed the live circuit. Instantly I would be part of the circuit. My shoes are rated for 500 volts. So the voltage potential across me and ground would be 3600 volts. My bodies resistance when dry is 100Kohms. However, If I sweat it's only 1000 ohms.
Now the 50,000 volt accident occurred when I was playing with my High voltage DC power supply. A free wire came loose and the potential difference was enough to statically attract the wire to my hand. So the wire jumped and grabbed me. My body resistance was normal, but that doesn't matter at that voltage. Because electricity can jump several inches to ground. However, my DC power supply can only give 5mA of current continuously. So it shorted out.
Voltage = Current * Resistance Power = Current * Voltage We unfortunately do not have a means of building a power supply which controls current and voltage at the same time.
How lightning and sparks act, cut down to basic: The readon of an arc is becouse of too much voltage in on one of the poles. When the level of electricity reaches this level, it breaks the density of the air surrounding it, causing an arc. The arc allways travel towards the opposite pole(+ --> - and - --> +) So therefore if you were to run trough the space between the tesla coil's, you'll be toast
So best case scenario there's 36 mA flowing through me. Worst case there's 3.6 amps flowing through me. Now comes the fun. If the electricity hasn't effected my muscle control I can break free from the circuit. If it is too strong I become stuck. So at 3.6 amps my flesh begins to cook a little in spots. Burnt flesh conducts even better. My body resistance drops, more amperage equals more burning. I just literally cook on the circuit.
Well the current would cause the damage. So the more current the more electrons flowing through a given area and the hotter something gets. It wouldn't matter if the person is soaked or not in this example since you've now bypassed the resistive skin and gone directly into the flesh and blood. The only problem with your experiment is it's impossible. Resistance determines amperage for a given voltage (or voltage for a given amperage).
Hey - great work - thank You. But - don´t You Think 144p is a little bit very very very old school and needs an update ?? It would be great ... Greetings from Germany
@thewii552 Why would the step-up transformer be 3 phase? I assume it is 480vac split/single phase? The coil itself is a single transformer, generating a high frequency, high voltage, single phase.
Yes a lightning bolt has around 1billion volts and this only has 5million but a lightning bolt strikes from nothing and only shoots every few seconds for a while and this can shoot a few ever second and could go on for ages so this would be the more harmful by far
If any of that current passes through my heart be it .03 amps or 3.6 amps my heart has probably stopped. But my brain is still active and I can feel pain for several minutes with my heart stopped. By the time 4000 amps is achieved my body is burning. So there are many factors in electrocution. Your body resistance, circuit power ratings, voltages present, and how long you're part of the circuit.
@shmackahippie i am not sure. only that way would make sure is what I said. Unless the guy is saying that each coil is one phase (when running out of phase) and the primary step-up is one phase...it really doesn't make sense...
So a 120 Volt 20 amp outlet will only produce a little less than 2 amps at 1200 volts. Now I've shocked myself with 120 volts ac and 50,000 volts dc. Why am I not dead. Well the 120 volt shocks occurred when my body resistance was normal. I wasn't wet and my body wasn't sufficiently grounded. If my body's resistance was low enough the 20 amp circuit could have provided enough current to kill me.
I think it's energy well spent. But seriously, Yeah, I know about what he was really trying for. But for many, that's not what really appeals to them about the Tesla coil. Anyhow, it was more of a joke than anything else.
@Luciferdesrea Actually, a TC can't kill you by electrocution. Since it's high frequency, the power flows on the surface of your skin and not thru it. It might still burn you to death though,
Like I said, your experiment is impossible. If both subjects have the same resistance then the more voltage you put the more current. So if current and voltage both increase the wattage increases. So technically yes, wattage kills, but it's the current not the voltage that will cause the damage. Moving electrons generate heat. They bump into things and they create magnetic fields. If there are more electrons from an outside source then your brain the body can't decipher signals from noise.

What amazes me most about this video is all the people trying to take photos with a flash.
Big, Bold and Beautiful! A "Current" 5 star video!

I know they had better camera quality than this in 07, right?

Why has no one decided to build a giant tesla coil over a hundred feet tall yet?
Tesla himself tried until he ran out of money! Let's realize his dream and build one!

I bet Tesla was smiling down on that display.

Alien Mother would say: "At this age, they always like to play with matches" =P
I wonder how that effects Aircraft Radio which is AM when we have lightning here can hear a pop on AM radio just for a MS this is continues

That would be something amazing to see for real... wish I was there, music ain't bad either.
A tesla coil can play music
aww, i wanted to see them connect for a while... not just for a moment..
Swarm leader: Do NOT cross
Well, Tesla coils are harmless.
What are they used for, at least the real tesla could probly light a entyre city safe from miles away
now thats a home security system !!! put one of those on the four corners of your property with motion detectors, :)

This is 5 million volts.
An average lightning bolt has 1 BILLION volts.
but would that look NEARLY as cool? Come on, Tesla.
They think we were doing that 10 million years ago
so manny use's for this tecnology oh god!
Curious how the video subtitles "480 volts of 3 phase AC" ... A Tesla coil is a single-phase, high fq transformer :)
Well the current would cause the damage. So the more current the more electrons flowing through a given area and the hotter something gets. It wouldn't matter if the person is soaked or not in this example since you've now bypassed the resistive skin and gone directly into the flesh and blood.

Thanks.
I could use these in my yard to get rid of the damn bugs.
Tesla vs Aliens...guess who wins? :)
Ahhh so thats what he was on about when he said it was over 9000
Hey - great work - thank You. But - don´t You Think 144p is a little bit very very very old school and needs an update ?? It would be great ...

Who needs a wall?
@thewii552 Why would the step-up transformer be 3 phase? I assume it is 480vac split/single phase? The coil itself is a single transformer, generating a high frequency, high voltage, single phase.
and remember kids:
don't cross the streams
i wonder what would happen if they did that in the sky directed to the ground in a thunderstorm or on the ground when connected to the mains ..
Yes a lightning bolt has around 1billion volts and this only has 5million but a lightning bolt strikes from nothing and only shoots every few seconds for a while and this can shoot a few ever second and could go on for ages so this would be the more harmful by far
@shmackahippie that is the input to the step-up
If any of that current passes through my heart be it .03 amps or 3.6 amps my heart has probably stopped. But my brain is still active and I can feel pain for several minutes with my heart stopped.

wow lucky chore for whoever wound those secondaries...
We should harness the electric power of lighting those bolts would power us for years since they are 100time bigger
so if i were to run through the tesla coils, would i attract the electric thingies, or would they keep hitting random places?
REd alert 2 in action
its like red alert the game
WOOSH! a hole between dimensions! xD
would you disentgrate when you touch the stream of blue death?
eeek, now i see why the camera guy is so far away.
Was that there source of power like everything wireless?
The Aliens?
this is electrolove!
You could probably find it somewhere on RUclips. Just look up Tesla Coil and Command and Conquer Red Alert 2.
@roderik1990 even if we have a hftc??
So a 120 Volt 20 amp outlet will only produce a little less than 2 amps at 1200 volts. Now I've shocked myself with 120 volts ac and 50,000 volts dc. Why am I not dead. Well the 120 volt shocks occurred when my body resistance was normal. I wasn't wet and my body wasn't sufficiently grounded. If my body's resistance was low enough the 20 amp circuit could have provided enough current to kill me.
:D i LOVE THAT GAME!
makes me think about paraworld (=
I think it's energy well spent.
But seriously, Yeah, I know about what he was really trying for. But for many, that's not what really appeals to them about the Tesla coil. Anyhow, it was more of a joke than anything else.
Where's ArcAttack when you need them?
wonder what would happen to a bird that flew between them...
@Luciferdesrea Actually, a TC can't kill you by electrocution. Since it's high frequency, the power flows on the surface of your skin and not thru it. It might still burn you to death though,
Until they are harnessed in such a fashion that they are used like in Red Alert.
Wow, Tesla sounds much better on their album, was there an equipment failier? were their amps not plugged in??
j/k ;)
Ahh de ott lettem volna ..ahh I wish I would be there ..
Never seen Red Alert.

"Twin" coils?
They aren't even properly tuned or synced.
Which gives 21.6 mA.
@roderik1990 Who you gonna call?
but their shock isn't deadly :(
@roderik1990 I wanna get a couple of these things at the front of my house to keep out the tax collectors.
if thats the case they should use them at the border
not the worlds largest
the worlds largest is at the Mid America Museum in Hot Springs Arkansas
That has to smell HORRIBLE.
I like the smell of ozone!
suck to get hit by on of those
@ogschizo lol, real men use DC
