Hi. That has to be one of the best comment I have ever read so far. Thank you for this video Drew, keep it up.

Nice job, I'm glad you've taking interest in Tesla's work. There's lots more unfinished work he never had the time for. His creativity is unmatched in the field. Keep up the good work. !!

Sir, can you please send me the theory of construction of primary and secondary coils in Tesla Coil

Excellent explanation for how Battery, Transformers and Capacitors work.

In Nikola Tesla's 1892 lecture he indicates more success with generators than with the spark gap method for some operations. Also his diagrams have single loop primary actually connected to the secondary.

I completely agree. This was a learning experience for myself to make a physics video for school. I had no idea it would get this many views to teach this many people. I used words like complicated and theoretical because I was burned out from research and wasn't sure on the accuracy of what I was saying. I was trying to convince my teacher, not teach strangers. I'm about 40% done with a reboot of this video, the next 40%is the most difficult part, though. Hopefully I finish it soon. Thanks.

This situation brings up a similar incident involving William R. Lyne and his proposed method of voltage - coil suspension from a Nikola Tesla method which was tried at a school science fair or show and tell or perhaps assignment in which the teacher said the method was the official T T Brown method.

Looked all over the Internet for a simple explanation of this. And failed until I stumbled onto this video. Props my good man, great job.

I know, it was a pain in the butt to find all this information. It was difficult to find the information that broke it down into "dumb-speak." There were equations about why it worked and home videos on how to make it yourself, but very few that broke it down. The swing comparison was the best way to describe how it works, and that GIF image did a good job incorporating it.

The dielectric break down voltage of air is 10,000 volts per centimeter. Not 1,000 per inch.

10,000 volts to arc one inch not 1,000. Can be up to 30,000 depending on conditions.

No need to start over. The currents in the secondary coil are very low - a few milliamps at most. That is why the wire can be so thin in diameter. Just solder the wire and continue. It could simply be wrapped together, but it is desirable to avoid sharp points which would encourage an air discharge at the point. Also, the solder makes sure the sprayed on insulation coating will not be able to get into the joint.

Hello there; I made the tesla coil, the features of which are written below, but the spark coming out of the top load is 3 cm. What should I do to increase the output spark length?

I really like your animated diagram of the magnetic fields building and then collapsing. Nice work!

I certainly did learn a few things watching this video I have been a long fan of Tesla and I haven't quite understood the relationship between the spark gap and capacitor until this point and of course now it is all clear but one thing I was waiting for is the point of high frequency electricity which you really didn't get to I for one am very interested in the effects of high frequency electricity thank you

You are a the smartest guy I've seen describe this and the basic comparison with the pictures and videos is an even greater effect. Keep at it you're the next college professor!

I have a microwave Transformer and capacitor. My Transformer has three wires on one side 2 on the other what's the third wire for the three sided Transformer?

You may want to double check that information. Alternating current is used to power most households since it's significantly easier to transport in large amounts. Direct current is generally used in battery operated devices since it's more efficient on the small scale.

Thanks for the nice video. Important question (useful for all) : In your circuit, the condenser is in parallel. Therefore when the spark gap in lighting (is on - closing) the high voltage will also go through the secondary coil of the input transformer. That can just damage it seriously. Is not it much better to have the spark gap in parallel (and the condenser in series) so this high voltage loop will not go through the secondary coil of the input transformer ? Please can you (Drew Colpurs and anyone who knows) clarify this ? Very much appreciated.

Great video. You explained very well how the Tesla Coil works. I'd like to know, though, what kind of bulb and if it has a filament, and what from Tesla's hand is generating the light. (Looks like everybody knows except me.)

The next question. The filter capacitor at 7200volts. The picture show a electrolyt. Is that correct? A electrolyt have a positive and a negitve pole but the 7200 is alternating, right.

Thank you very much for your video here. I would like to know more about the longitudinal scalar wave propagation of Nikola Tesla, and the relation between his radiant energy concept. Can you tell us something about that? Is there a longitudinal wave between the transmitter and receiver, or a kind of displacement current between the aerial capacitors of a Tesla signaling system, may I ask you?

@JenkoRun

Жыл бұрын

From what I understand Longitudinal Impulses are formed when the frequency becomes so high that the magnetic field has no time to form, as a result the energy takes on a wave form that has no transverse component, without the transverse component these longitudinal waves don't cause hysteresis in the Aether, meaning they experience no time or lag in their propagation and are not subject to the inverse square law. This is why they have practically unlimited range and no time delay. Think of how a tidal wave works, when it starts it has barely any transverse motion to it, and as it propagates out across the ocean it gains strength and maintains a mainly longitudinal form, it's not until it hits shore that it takes on a more transverse form, this is also the reason why Tesla stated that the propagation would become stronger with distance.

What can you say about the energy of these longitudinal aether-waves ? What do you mean by high frequencies, a Tesla Coil can be built in kHz or MHz values, on the other side we have Hertzian Dipoles which produce in many hundreds of MHz values but still transversal in its nature, hmmmm…… How does a Tesla coil produce these longitudinal waves, am I right here, if compared with an ordinary Hertzian dipole? As far as I understand, in a Tesla coil, the magnetic field component (primary and secondary coils) is separated from the electric field component (aerial capacitor) the electric field component may refer to these waves in the aether (longitudinal waves) is it possible to say that, approximately ? A Tesla coil may be used to tap into this aether energy field, am I right here ? An ordinary (Hertzian Dipole) receiver would not respond to these longitudinal wave components, but a Tesla coil would. Is there a possibility to transform a Tesla coil into an aether-energy receiving system?

Am I wrong or is the video wrong at 2:11...the outgoing and incoming should be reversed..??

Couldn't you attach the capacitor to the opposite side of your tesla diagram and make a radiant energy tower out of the toris and reverse the operation to create useful AC current?

If you want to calculate voltage by using a spark gap, you need to use the formula distance in millimetres the spark can jump x 3,000 V or distance in centimetres x 30 kV

I'm very cool at all what have you been able to make two Tesla coils and sent energy in between each other

A look at the Tesla 1891 experiment might be interesting as cylinder coils are used and the 24/7 power from Hemisphere 'bulb' of solid aluminum is another experiment worthy of illustration. Also my way of doing things but that neither here or there.

+DougRH Henderson Haha. Nope, we had no such toy in my high school but point taken. Thanks.

alternating current allows electricity to reach your house. Appliances are usually D.C because of the very short distance from source to appliance. However alternating current holds it's load, and voltage can be boosted to push the current through long distance cabling. With D.C the current simply suffers too much volt drop and and can't push itself far enough to reach everyone, from this i also guess it can't maintain the ampage it needs. Substations/transformers are used to push A.C current through from the powerstation, A 400KV supergrid would put the current through several step down transformers so when it reaches your house it's not at 400KV but 230V. A.C current is produced by using slip rings while D.C current is created through carbon brushes and commutators. This is all industrial stuff but if anyones interested in learning about electrics hope this helps a little!

Not exactly true. AC has the advantage that voltages can be easily increased or decreased - at high efficiency. With DC, conversions are expensive. Most appliances run on AC, although most electronic circuits require DC, so the AC is converted to DC inside the device. DC is actually more efficient than AC, even for long distance transmission - if the voltages are identical. But the voltage conversion problem I mentioned above makes it impractical for anything except very high voltage transmission lines. The reason it is more efficient is that there are no hysteresis losses with DC power.

Insanely good video.

good video - but I wonder what the purpose was? - send power to the ionosphere to be tapped on the other side of the globe?

Don't you understand that the spark gap was used to produce wide spectrum of electromagnetic waves which are separated to those which cause a resonance of a big coil+cap on top? This important thing is ignored by almost of everybody who tries to repeat the device. They try to replace the spark gap with modern silicon valves.

I’m still watching but noticed you said 1,000 v per inch of arc in the air... I believe it’s more.. a lot more.. closer to 75,000 v to arc in clean air, or 3,000 per mm.. but it drops after initial ionizing for a sustained arc.

How does the tesla coil cause wireles electricity to power a lightbulb far away?

Electricity is the flow of electrons. Lightning is electricity that overcomes the natural resistance of air to pass electrons from one atom to the next (since air is gaseous, which is naturally very far apart, and most gasses in our atmosphere are relatively stable, this requires a large amount of voltage, aka push on the electrons). When the voltage is high enough to create lightning, a current of electrons can be passed from the power source (such as a tesla coil) to something accepting a current, like a light bulb, causing it to light up. Does that help?

Spirit Soul You're referring to things I've never heard of, but in terms of practical applications of tesla coils, they're not practical. Anything in the path of the current would be fried, there's no way to maintain a steady current, and the amperage would be quite low. In terms of Bearden, I've never heard of him.

You fell apart a little on trying to explain capacitors but I'm not sure how I'd do it either... I would correct you however on one aspect. Capacitors CAN hold a charge indefinitely. In fact you should always discharge capacitors with an appropriate resistor before touching them. Also I'm not sure if you mentioned that capacitors OPPOSE a change in current which is why you need them in parallel with your coil. Without that capacitor you could very well vaporize everything.

Actually it’s not so complicated as one may think . The challenge was back in his time there was no ready made components and he actually had to build most parts like capacitors that didn’t exist according to his calculations

In prep for next video, please seek out retired Thomas Bearden video where he says that he didn't meet Tesla but met his nephew (who found his body and noticed his current notebooks missing. While there Trumps Uncle shows up with trucks to take Tesla's documents.) Point about Tom Bearden meeting the nephew is that he rode with his uncle in his free energy electric Packard Bell on the Long Island parkways!
