Ben is right. It's a principle called reactive power limiting. It works the same way as resistive power limiting, but with capacitors. Pretty basic electrical theory. I realize this post is way old but still wanted to clarify for others.
well it cant be a capacitor because its way too dangerous to use in demos like this and why he dosnt discharge everytime the setup changes ? i dont hear the snap sound from a capacitor discharge !
@@incrediblemichael This is AC, you can hear from the humming. The idea of "charging" and "discharging" a capacitor, in the sense of "no it would just dangerously discharge instantly and then it wouldn't sustain any longer" only applies to charging a cap with DC voltage.
He was talking about treehouses, and I was thinking "It's 2021, children do not what playing outside is anymore." Then I realized it was dated 2014 before there were 30 apps called treehouse.
I really do wonder if kids even know what treehouses are and if they ever want to build one or visit one these days... 2014 isn't so long ago but I do believe the phone technology and other entertainment devices have taken over the youngest minds as of late with social media and other apps, it's really sad. I hope our future isn't doomed by it...
Teaching kids about electricity and electrical safety saves live. I learned about electricity the hard way.....Could have save myself some pain with proper indoctrination.
If kids have food in the gym it will be awful. My hs gym doubles as the basket ball court for games and the stands always had nasty crap in them. But that is unnecessary going that far.
They didn't. They run a pole transformer in reverse, feeding 120/240 volts into what is normally the secondary winding, which steps the voltage up to primary distribution level (7200 volts).
And the way this demo works is exactly what happens if you hook up a generator to your house wiring without a transfer switch. Electricity backfeeds through the meter, up the service drop, and into the transformer, gets stepped up to primary voltage, and electrocutes someone.
@@bamaslamma1003 my transfer switch is just the main circuit breaker. It seems to work ok when running my generator. I dont think I've killed anyone yet....
Nah its fine. Its not like the kids were jumping at the line lol. There was also a switch immediately nearby. Their eyes don't hurt when the room is bright, speaking from.experience.
Stop being paranoid. These are professional electricians, don’t you think they would have thought of that if that was a real big concern? I am an electrician myself and I would not think twice if they had this setup at my kid’s school. Also, the arc would need to be continuous and you would need to be staring at the arc to make even the littlest of damage.
