The Crazy World of AC Electricity #shorts

This is a clip from my next video, where I challenge Veritasium's answer to his question on the "The Big Misconception About Electricity". Stay tuned! #shorts

AC is just DC that keeps changing its mind.

[tommihommi]

ah yes, the loop on the ground is a ground loop

[MrHeuvaladao]

Yeah, air conditioners are really crazy.

The wire is long enough to cause a phase difference, the wavelength is around 60 cm, so if one chooses appropriate length of the wire, one can create a potential difference across the two ends.

hell yeah "free" energy, finally, i knew you could do it mehdi!

[ChloePricesNumberOneSimp]

My dumb ass was waiting for him to show the air conditioner.

[Ziar]

Bro just created an antenna and is gonna have the Canadian FCC on his doorstep

I feel like "The world of AC" is not actually that great to combine with "Shorts", no matter how good this video is. I generally try to avoid AC shorts...

Oh boy, #shorts takes on an entirely new meaning when it comes to ElectroBOOM videos.

How does this happen?

Because of the speed of light, a 5mhz signal will have a wave length of about 60 meters with peeks seperated by 30 meters. In a copper wire, one wavelength would be a about a third less or 40 meters where a 1/2 wavelength is 20 meters.

This loop with an LED is maybe 3 or meters. 3 meters is about 15% of 20 meters and 20 meters would be equal to 180 degrees of a wave. So the loop represents 15% of 180 degrees = 27 degrees phase difference. and cosin(0 degrees) - cosin(27 degrees) results in a voltage difference that peeks at about (+ and-) 10.899% of the signal.

In other words, A 5mhz at 10v(peek) signal would generate about 1.09v(peek). Since a white LED needs about 3.3v to 4v, the driving signal might have been between 33v- 40v (guesimating).

That long loop some capacitance. That serves as a virtual ground.

[SeanHodgins]

I have some ICs from a small company that are meant for "AC harvesting" I haven't done anything with them yet.

[robstamm]

If you touch a grounded led in complete darkness you can sometimes see it light up from the radiation of the mains wiring in the house - but don't tell anyone with fear from "electric smog/pollution" ;-)

[LoppyDaCutie]

The sky looks clear today i wonder if it will rain tomorrow

[sheiladawg]

The LED turns on because a 5 MHz signal would have a loss through the cable high enough to create a potential drop to turn it on.

[seancsnm]

Reminds me when I picked up an AM radio station through a stepper motor... High frequency AC is the most elusive area of EE. I really need to go back and study it some more.

Never has the "shorts" hashtag been more appropriate.
