L C Resonance etc.

If anyone can endure this guy then you should be nominated for a medal, I lasted about 5 minutes...

Hard work tolerating him, isn't it?
I did notice how the uses L for inductance, but then draws the letter Z: hmm. Anyway, apart from all that, to me, that was a good example of how to explain something that is relatively simple in an exceedingly complex manner. Each to his own, sure, but a few graph / phasor diagrams and a bit of basic mathematics not only gives a far better explanation of resonance but is also a lot shorter in duration. And, as a bonus, you can then digest that analysis at your own speed - unlike that presentation, where I felt that I was on a Formula One race-track!

Yes that blokes mutterings drew the attention of my other half and she asked do you have to listen to that, enough said.

Yes, that bloke's mutterings drew the attention of my other half and she asked: "Do you have to listen to that?" Enough said.

Lawrence.

"Mutterings", eh? I would have used the word 'ravings'.
Yes, enough said.

Hi Al, I find that you have to sample a lot of videos on utube before finding any that are any good from a learning point of view.

Agreed, Lawrence, agreed.
Yes, I can understand that there are some people who enjoy being a teacher but that doesn't mean that the ability to make an informative 'lecture' automatically follows as a consequence.
Each to his own, sure, but I'm a member of The Old School: I prefer to learn from an authoritative text book. Having said that, it is my experience that the vast majority of text books on Electronics, Physics and Mathematics are badly written - especially the author's command of the English Language: frequently abysmal. Then on top of that in the Radio and Electronics category, there are the technical errors - sometimes serious ones, too.

Yes, old style for me too, this is my kind of tutorial, a brief modern intro to the film then the old style lecture follows, basics of parallel L C R circuit with practical demo near the end. (Film in black and white)
