Mechanical vs Electrical Resonance and How a Tesla Coil Works

[xassxass]

those aluminium disk.. what made them suddenly react?

[kdc43]

@xassxass He explains it in the vid. Dump the capacitor power thru a coil to generate the 1st mag field which surrounds the disks. In doing so it "induces" a current in the disk which generates a 2nd magnetic field. These two fields fight and oppose each other and they want to get away from each other......so the disk shoots up and hits the ceiling.

Very well explained...... I didn't get the idea of Resonance during my B.E but now it is clear

[ashtonmorris]

No offense but this guy seems like a real douche.

I like to demonstrate resonance with a flagpole. if you shake it at the right frequency, you can get it to bend and wave back and forth really far.

i love the geek group im almost 13 and i haven't seen any thing with the geek group on it but i do at least have a way to get online and want to know more of what the geek group does before i join and one i join i want to do something so what does the geek group do most of the time and how old do you have to be and in Minnesota is the a chapter the geek group please respond i will most likely be posting this on a few geek group vids but i dont want to spam it thank you

those "3 small caps" in the ring launcher aren't all that small...

[drkbltn]

@thewii552

If you compare it to what you find in the industry (substations etc.) Those are small...

Does the box with the power supply and capacitors @ 2:25 have a name? Or do you have a video about that? I'd really like to make one for when I teach about electricity and magnetism. I would like to learn more about it's math and construction.

I'm learning about capacitors in school right now, and I was wondering...

If you kept holding that button down, supplying charge to the capacitors, would it eventually discharge on its own?

[williefleete]

@pt2091 the charge in a capacitor will theoretically hold indefinitely until discharged or a load is placed on them and high voltage capacitors will have warnings as they WILL bite if they have a charge on them even after turned off for a while

[Balarick]

@pt2091 capacitors have a limit. when they fill you should release the switch.

I did science at school (and I'm no idiot) but I NEVER understood how a Tesla coil worked. Black magick to me!

Boden's explanation of the principles behind all of this suddenly made it clear to me, 10 years after I last did science in school. Thanks TGG ;)

[ZephyrLabsEst]

Great explanation!

[Rodgerrynd08]

Fantastic video, Bill Nye has NOTHING on Chris "Gimmi da baseball bat" boden.

[shintsu01]

GOOD stuff i dont know mutch about tesla coils but your explanation made the basics quite clear to me :) thank you for that

[fbpoulsen]

Nice!

[m3sca1]

good description also the secondary is tuned to a quarter wavelength of the primary-so that the largest swing of the "pendulum"is expressed at the top of the secondary,and if well tuned the bottom of the secondary should be pretty close to zero volts.

if you imagine a skipping rope in motion then that would be half wave and the highest volts/amplitude is in the middle,and the lowest at the ends-but if you could somehow cut it in half and still keep it in motion then that would be quarter wave

[NewfDraggie]

Flawless explanation.

[HomeDistiller]

best "on the fly" explanation of a TC I've seen

[enderwigginsx]

SCIENCE RULES!!

Thanks for the lesson!

BILL BILL BILL BILL BILL BILL-

BILL NYE THE SCIENCE GUY
