Understanding Power Supplies, Generators, AC and DC.

[aswayb]

I am thinking seriously about training as an electrician. I have no previous knowledge in this area and so I am a little wary. However I found this video very well presented. Many thanks uploader

i'm just starting out in electronics, having watched numerous courses from several people on youtube here, and i have to say, you're hands on approach and explanations have been the best that i've seen. Keep up the great videos you've definitely gained an avid subscriber today! Thanks again.

I too enjoy your ability to explain somewhat complex configurations in a down to earth simple way. Love the visual aids

[1stheangelshare]

Brilliant in it's clarity and simplicity. Your vid put the cap on my understanding of the principles of the subject. Your visual aids could not have been better imo. Thank you teacher: you just got another subscribee :-]

Hi Mike -

Greetings from NJ. You have done a great job explaining the principles behind switching power supplies. Kudos to you. Just a bit of correction: it's 'sine' wave, not 'sign'. In any case, I'll continue to be a loyal subscriber. Never been to Oregon but judging from your other videos, it must be awesome! Let me know if you're ever in NJ! - Nelson

@nlimchua Nelson Thanks for pointing that out. God bless.

@GrantsPassTVRepairs Dave, I've also been playing around with crystal resonance testing. Normally, a dipmeter would work great by itself or with a scope; I also found that you could use a function generator's center wire (with a small ext. wire as antenna) to tickle the resonance of the crystal and view the peak on the scope. Thought I'd share that.

All the best,

Nelson

PS> errata on my earlier comment, I meant 'Dave'! (sorry)

[GrantsPassTVRepairs]

@nlimchua I also have a dip meter but I never used it to test crystals. Thanks for the info.

[nlimchua]

@GrantsPassTVRepairs I know what you mean. I've had my dipmeter for almost 10 years but never really got around to play with it. With the job market the way it is today, I've had more time to spend with electronics and enjoying catching up with what I've been missing. I noticed you're much into the hobby too (with your crystal radio, etc). Check out youtuber, Allamericanfiveradio (Rick), he's a treasurechest of how-to's.
