Unless the DC is produced via a rectifier and the AC used to produce it varies wildly... that's why we have capacitors and voltage regulators, though =)
@@mtark9988how it works like a solid state valve? 🤯. Experts explanation to common people: well you know NP junction sex between two types of semiconductors male and female. 🤣
And the fact that if you put two valves back to back blocking each direction, you suddenly get a transistor, which allows water to flow completely unrestricted. That's some black magic.
@@phillyphakename1255 not really You put pressure in the middle and it allows the valves to open Think of the valves having an extra mechanism which opens when pressure hits it
I like how I’m in automotive tech class, and rn I’m doing the electronic parts of it, RU-vid decides to recommended these to me which help a lot. Thanks for the videos
I often wonder if there are other hypothetical electrical components that would be useful but that nobody has thought of, or that we just don't know how to make.. Or do we know for certain that all the simple components that we _could_ make we have already made?
Of course there'll be electrical components that we haven't yet discovered their usefulness in electronic circuits... There's a plethora of combinations of elements that haven't been tried in circuits and some with potential are not yet mass produced so the cost still outweighs the benefits...
One is Memristor,.....and there can be many. While studying especially 'Theory of Electrical Elements and Components' in Electrical Engg. you will come to know about many mathematically possible and physically realized systems based on that.
@@ItsdirtnaptimeIt’s to keep you in an endless loop of watching the RU-vid shot Idk why people do this tho cause I don’t think I give and extra view Unless I’m wrong and it does give extra views….
Thanks for your very clear and simple explanation of a diode. I studied Electronic Engineering 30 years ago and your explanation is very easy to understand and spot on. I wish we were taught like this back in the day. I look forward to more of your electronic component explanations as it reminds me of the old days. Thanks.
It's not that easy lol. When diode is forward biased, there's - Injection of charge carriers (holes at P side, electrons at N side). - Subsequent diffusion (movement of charge carriers due to concentration gradient, i.e. holes move away from P side & towards N side, meanwhile electrons move asay from N side & towards P side) - Drift (movement of charge carriers due to electric field) - Recombination (because hole cannot carry longer in N side & electrons cannot last longer in P side) All above keeps happening. When diode is reverse biased, - Even when diode is unbiased, naturally holes move from P to N region and electrons move from N to P. - This diffusion causes recombination of holes & electrons (thus no charge carriers at junction). - Once few carriers are moved, some atoms are ionized & it creates electric field internally (which should be overcome to flow current, that's why diodes have threshold/knee voltage) & Further no diffusion is possible. - By reverse bias, this gets even worse (like opposite of carrier injection). Carriers move away from junction & hence depletion width increases even more, hence no way to flow current)
Some professors are obsessed with formulas, graphs but this is of no use if the student does not even understand the working principle. Start there, explain for even a child to understand and this way you make the student curious what stands behind the scenes (formulas, graphs etc...)
MY THOUGHTS THE SAME...MAN!!!! I WISH I HAD THIS SIMPLER DETAIL CLARIFICATION EONS AGO....FOR US FOLKS WHOM DEFINITELY THEORY AND PRACTICAL APPLICATIONS WOULDN'T SQUARE TECHNICALLY .🤔🤯🤦😄😒
Well, yes and no.. A transistor isn't really a "diode plus diode" as much as it's a "diodediode" (or really more of a "diodeedoid", I guess?). It only works if all of the component pieces are right next to each other in a single piece of silicon (and are the right sizes and have specific contact areas, etc), so you can't just take two diodes like these and wire them together and get a transistor (unfortunately).
that is a little misleading but, in terms of water pipes you can still think of transistor as a manual valve instead of a swing valve by placing two valves (like the one in the short) opposite to each other but they would have to be operated manually by pulling the gates with some sort of handle or rope. but just putting two of these at a distance with out any type of control over their gates, wouldn't really work or pass any water.
@@Ali_Massoud except that the rope should be replaced with a water mechanism because transistor require electricity in middle pin And weird stuff can happen if you wire it up wrong
very recently a HUUGE power surge happened to the house. It keeps happening. The 52" TV died. Just about to purchase new replacement guts for it But I purchasd an inexpensive UPS (uninteruptible power supply. basically a power strip with a battery). Everything on the 52" TV came back to life! The rectifier system made everything work! Diodes are amazing
I've spent my career in industrial electronics. I've seen some very big diodes! A "hockey puck" diode which passes 1200 amps is compressed between two water cooled heat sinks.
Brought me back to 9th grade... Subject called "building elements" First of them all is this litle guy with the so important PN преход.... It should be PN gateway? 😂 Entrance? PN portal 😂😂😂
The swing gate has a stiff spring holding it closed, just a little pressure can’t overcome it and flow but increase the pressure and it can overcome the spring though there is a drop in pressure. That is the forward voltage drop of the diode.
“it will break if we exceed its limits” aka it becomes a fuse. thats why LED christmas lights don’t need a fuse for every bulb like in the 90’s, they’re their own fuses
This channel is awesome, i dont know why but my brain just can’t handle elctronic knowledge and this channel is what i looking for a very very long time
If a reverse voltage is applied to the diode, it blocks. This changes the capacity at the blocked area (capacitance diode). But if the maximum voltage is exceeded, then the diode also conducts reverse flow. (Zener diode). This can then destroy the diode.
Thank you for this... Now i know what diode use for. Is just like when a DC battery accidentally puts a wrong polarity and that diode protects all component
ahhh thanks for explaining.. never understoo what a diode really was and was always wondering how i could make a closed circuit board if i couldn't make sure how to prevent electricity from flowing back to the components.. like flash capacitors..
Diodes/rectifiers are used prominently in the field of cathodic protection, to protect pipelines, underground storage tanks, etc., from corrosion. This was my career for 32 years. Most people have no idea what it is.
Tell me one thing that doenst break if you pass the limits… Also, its ok to make 1 example of how a water one way valve works, but then show a image if the diode actually working… diodes dont have valves..
Your shorts are amazing! I would love to understand electricity better. These shorts have helped me immensely. I'm going to start on the full-length videos next!
Diodes are fantastic, i tried to "make" them in Minecraft and in computer logic and are absolutely fantastic as how theire useful, well not were i recreated them, but in the projects i made, it makes a project a bit more expansive, but its a chad component 9/10
Interesting analogy to Water. What if we were to use Rectifier Water Valves to cause Ocean waves or tides to force woter flow into a pipe in one direction? Perhaps in Holland to drive the pumps that keep holland dry. Of course it could be used anywhere next to the oceans as an energy source. Perhaps even driving Electric Generators from this Rectifieed water flow. You might even use it on a ship at sea or yacht to generate spare electricity. Yet another way to capture otherwise wasted Energy.
This is why those videos were people saying not to blow out your pc cause the fans will create voltage. These kinda prevent that from happening. Blow away!
