ARCS! Frame by Frame

One can learn a lot about electric arcs seeing them at 1.75 million frames per second. Let's analyze!

Below are my Super Patrons with support to the extreme!

Hi all! Just to be clear, when I say high voltage I don't mean positive voltage. Remember Tesla coil has an AC output. High voltage here means high positive and negative. If I show signs, it means a momentary difference in voltage which will switch the other way quickly. The direction of electron flow is alternating in and out of the Tesla Coil, but the way arcs are expanding doesn't alternate, because other factors cause the expansion as I explained. The glowing arc is only a sign of air heating up, and as the charges break new grounds, new paths emerge.

Electroboom: 1.75 million fps? That’s a good starting point.

hope everyone back in Iran stays safe Mehdi. Every Persian I've met throughout my journey as shown to be incredible people far removed from the autocratic clerics running the country Stay strong

[frollard]

Equalizing charges, and equalizing human rights...all in one place. Brilliant, purely brilliant.

Mehdi doesn't often get political on his channel, but when he does it's for a really good reason

[Xnoob]

1:59 I'm glad you briefly touched the subject of current events in Iran. Respect.
Edit: 3:40
Respect.

Dude thanks for #MahsaAmini - lovely to see your support! Also, very cool collab with The Slow Mo Guys, it's the third video I'm watching and still loving it!

[PanduPoluan]

ElectroBOOM is probably the *_only_* YouTuber for whom I never skip the sponsor part. Because the sponsor part always have that nice music. Oh and also Mehdi always presented the part hilariously 😂

[briankelly]

Wait, I thought electrical arcs were free electrons so they were always negatively charged. How can it jump both directions? Are metal ions being pulled from the electrodes? Come to think of it, why doesn't it alternate jump directions?

[beansnrice]

Oh man, I suspected you were going to say something about the events in Iran and I'm glad I was correct. I'm so proud of the people in Iran and the media needs to talk about it more. It's not like i'm asking for western intervention but it's an important story for the whole world!

[FrankDrebin]

Could be fun to run 2 tesla coils, with one 180 degrees phase-shifted :)

Now I want to See Mehdi's Eyebrow wiggle at 1, 750, 000 FPS

[shadbakht]

I love your vocal support of the women in Iran! Thanks brother

[EEEEEE-wxwp]

Much support to Iran here. An Iraqi speaking here, the poor Irani people have suffered for too long. May Allah keep them safe

[richardpike]

The diagrams you drew for explaining the concepts like the "zone of ionized fluff" was really helpful for me to understand it! Great job

[willburk]

So could you power your coil through an isolation transformer and get it to generate arcs from both directions simultaneously?

[tonytwotoes]

would love to see this experiment carried out with both an active air flow to cool the air between the points of contact, and within a heated, windless environment

[GERntleMAN]

What I find truly mindblowing, is the speed physics has. Even 1, 75 million frames per second, which is ridiculous to begin with, isn't even enough to show a slow smooth moving arc. Or the collapse of a dying star in milliseconds. Just amazing

[arshiaabdi]

Seeing you share #MahsaAmini in the video made me very happy!

[chrisbranski]

10:30 the sounds of the arcs breaking trough molecules is extremely satisfying
