I agree, except when I was a kid in the 1970s there was nothing but buying books, or the town library (we haven't got that book, we can get it from another library, it will take two weeks...). No online, no modems of any speed. I found some old astronomy books from my youth (I was born in 1966) recently and was shocked at how little information they actually contained, and most of them had the same information as the others. A child today could learn more in twenty minutes on Wikipedia or watch instructive videos. These are wondrous times.

I am the age of 15 years, I've been interested in electrics since I almost got my self killed by touching the mains with a pin as a little child. I'm happy that all of this information is handed to us like an golden secret. It is quite sad to see that not that many of us want to spend an (min.) hour of researching.

The video has taken up 3 pages in my notebook (I'm in the learning/tinkering phase still) and now I FULLY UNDERSTAND what a bridge rectifier is, how it's made, how to build, all the components functions through the entire wave form and its benefits and limitations when applied to various types of builds/projects and when to and not to use one! 35 minutes ago I didn't have a clue what this "bridge rectification" alien technology was or what it was all about and now I feel way smarter because of an 11:19 video that I kept rewinding parts of and taking notes. Being smarter after a video doesn't happen often while watching KZitem! This is the gold standard of how/when/why/where electronics videos should be done. WELL DONE SIR! THANK SO YOU!

The lowest you could get is probably a USB one. You'd probably need to do some tricks to lower the voltages reliably if you deal with high voltage, but usable for low voltage applications and 20MHz bandwidth on the low end. They are not as good as things like a Rigol DS1000 series, but cheap and probably enough to start with.
Awesome video. Very clear and understandable. I'm currently building a dc power supply and this video helped a lot. I thought I had bridge rectifiers pretty much figured out but I never thought of it doubling the frequency. Thank you.

@expertu
3 жыл бұрын
Due to imperfections in the material, no two diodes are equal, thus their electrical parameters differ slightly. There will always be microscopic differences in the material density. The issue with putting diodes in parallel is that as they heat up, their resistance decreases. As a result, at one point, one diode ends up taking on a little more current then the other diode, resulting in it heating up even more. As you can probably see, this cycle will cause thermal run away causing that diode to eventually burn if you give it enough current.

Half wave rectification does have a wonderful use in resurrecting dead batteries! I've been using a half-wave rectifier with an incandescent bulb (to act as a current limiter) to rescue discarded batteries for years. The high voltage peaks serve to break down sulfur crystals on the plates and the zero voltage periods reduce the heat buildup and give the chemical reaction time to take place.

3:00 - this IS 5A diode, in theory. There is some variation, but as the forward voltage gets higher with current, other diodes start to conduct as well. In my car battery charger, I had four diodes in full bridge, but they kept burning. So I added four more in parallel and it worked. With BJTs, this is the same thing. It may not be the best, but it works.

I was surprised by what you said at 2:53. It not only seems like it would work, I've done it many times because I always have 1A diodes but few if any bigger ones lying around. If voltages are right there at the fwd voltage then I can see where one may flow while the other do not as your picture shows, but other than that unique scenario I don't see the issue so I was hoping you could expand on that. I've also done this with transistors where I had current near or exceeding the transistors capacity so I simply double them up. I assume if it's bad for a diode the same likely applies to a transistor? Never had an issue doing that either, only a solution to a problem which is again not having the correct parts. I must not be doing whatever it is that creates the actual problem but would love to know. Your vids are great btw! I love that you show what happens when you do something wrong, which explains so much more than just showing how to do something right.
