Excellent good vibes physics lectures!! Making it easy to comprehend.

[@SamFugarino]

Thanks Dr Anderson! Love physics and electronics.

[@yoprofmatt]

You are welcome! I like those too. Cheers, Dr. A

The circuit breaker is a great example. There's one I like, and it's also in one of my books, that illustrates the difference between AC & DC (current) for the same voltage.

[@yoprofmatt]

Thanks for sharing. Cheers, Dr. A

Are you having to also make more videos due to KZbin’s new terms and agreement’s? I enjoy all your videos, I have used your material to help create some of my prototypes. Thank you for your method of teaching.

[@yoprofmatt]

I remastered these to get rid of the annoying squeaks. I will try to keep making new ones in the future. Cheers, Dr. A

In Poland there was once (back in the old days) a series of fires because of circuit breakers and farmers that didn't know how to use them properly. They would lock them so they could no longer flip and that caused fires. Also another not so fun fact is that a lot of in-wall circuitry (at least in Poland) used to be made out of something else that is used now. This material (I don't want lie about a name, not sure) would evaporate after many years of usage. This caused problems in my house, because fire started inside a wall because of how hot shrunk wire got.

Wow, major bummer. Great tip: Definitely don't lock your circuit breakers in the closed position. Cheers, Dr. A

Incandescent bulbs use an argon/nitrogen mixture, rather than a vacuum. The majority of the gas is argon, to mitigate the oxidation of the tungsten and provide internal pressure on the glass surface. The nitrogen is added to improve the gas's ability to withstand electrical arcs, as this is one of the weaknesses of argon. I have not found an answer as to why pure nitrogen isn't used. Due to its abundance, I would expect it to be the most economical choice to use for an inert gas, when no other factors govern. While not in the family of inert gasses, it might as well be an inert gas due to how energy intensive it is to react it with anything.

From one nerd to another, I salute you. Cheers, Dr. A

They didn't have AC current back when Ohms Law was established only DC current...

[@carultch]

If you neglect inductive effects, Ohm's law works for AC circuits as well.

Excellent discussion, thanks. Cheers, Dr. A
