A FUUUUL BRIDGE RECTIFIER.
NOT a puny single diode rectifier.
You sir, are a connoisseur.
BOOM
I was about to say this, nice
electroboom
@@geoffsmith6373 yeah duh but it's a electroBoom reference
You don't mention the capacitor. I'm assuming it is there to keep a steady current flowing through the diodes during the switching?
Very much so, capacitance has always given the option of stability as well as directional pathways....brilliant little piece
The capacitance is added in parallel to the output in order to stabilize voltage on the output. Think of it as mitigating peaks and valleys when the diodes are switching.
If this was a higher current application then inductors would be added in series with the output as well.
I'm asking if adding any load will alter the path of electrons.
You are showing conventional current and not elecron flow as you say.
Correct. I noticed that too.
Thank you!
Because this was confusing me since the video before this...
Rectifier conversion of AC power to DC power

aww answered my question as to why they were flowing the way they were.
Wow, that animation told me the whole story. Thanks for demystifying this for me.
In your previous video about Diode, you showed exactly how the current flowed through diode. Please check and clarity that. Also, there's confusion sometimes when you say flow of current or electrons refering the same green dots flowing.
Please clarify these two things.
Thank you for taking your time to educate others on Electronic Theroy. Good People Teach Others Their Gifts and Wisdom
Hey mate, this is a fantastic demonstration. I'm studying aircraft systems and I've struggled to understand till now. Thanks for going through the effort to explain.
Haha same, have to study these for my aviation degree
Well you got this backwards, Electrons flow against the arrow. The Positive Holes (lack of electrons) flow with the arrows. Other than that you got it right. Thanks for sharing though. Best Wishes & Blessings. Keith Noneya
this is really useful. how about explaining how DC to AC works?
P.S. youre doing a great job sharing things with us, please keep up and hope more of us follow your channel!
Thank You! That's a great suggestion, I'll add that to my list :) And thank you for your encouragement. I hope more people follow me too! :D
@Julien Décarie Is there a problem
Its called a power inverter :)
Using a magnet that is spinning, with wire nearby, the north side pulls the electrons one way, the south side pulls them the opposite way. Thats how turbines turn mechanical energy into electricity
ruclips.net/video/n3d48PoPFkI/видео.html
Tytyty! I'm currently a new student studying Industrial Machining Controls! I absolutely love the simple explanation!!!!
What is the program that you use to design these circuits
Well, I understood it. That's a step up from some of the tutorials I've seen lately.
YES!!!! I UNDERSTAND!!!! THANK YOU SO MUCH!!! I just started studying at home and didn't understand this part, now I do! Thanks to you!
Light bulb just went off in my head. What a great visual demonstration.
FANTASTIC VIDEO, NOW i finally understand why the diodes are arranged this way! Thanks a lot.
I'm confused. On the other videos you posted with diodes in use, the flow is on the reverse direction. Are the diode symbols not reversed on this video? Electrons flow from the negative to the positive poles on a diode so which is the - side of a diode?
enjoy your videos.
Please refer to my video "Reversing Direction". there is a change in how I am demonstrating electron flow, moving to conventional flow. Thanks :)
This is great. It is perfect for a beginner or helping someone (like me) review a topic with a fresh perspective. Keep up the great work!
ruclips.net/video/n3d48PoPFkI/видео.html
The concept is simple. But to make it happen.....takes really smart people.
Many thanks
Im 54y surgeon ,but i i found this very simple and clear
This like avalve that works in on direction
Thanks. That was the best illustration of electron flow that I've seen. It was very helpful. (I still need to watch again...)
What software are you using? That would be helpful to know.
My pleasure! Subscribe to the channel for more of these videos. The software I am using is everycircuit, available as a web app or mobile app. everycircuit.com
This is not electron flow this is conventional current positive flow but same thing in practice
Hello! This lecture helped me so much since I’m taking electronics engineering. May I ask what software did you used in this demonstration?
Everycircuit.
Very nice explanation and EveryCircuit is a great tool (though the canvas is a bit small and I'd rather have it as a Windows application)!
If you'd call the diodes clockwise D12, D3, D6 and D9, I'd say the electrons returning from the cathode of the lowest LED have a choice, as they encounter 2 forward biased diodes: D3 and D6.
Same at the point where they went to D3, they could go to the forward biased D12, or they could go "left" back to the AC source. I don't see what determines the route of the electrons...
You know that what you called "elecrtrones flow" actually is the technical current direction, so it is the way a positive probe particle would go. It's clear because the diode diagram's arrow is always pointing - of course - in the technical current direction.
Yes this threw me off as well
Can anyone please tell what is that software he uses to demonstrate the circuits
Fantastic! I never knew how this works and now I do!
Very nice animation. Thank you from Texas.
This was explained so well! Good job!
Hi! At 4:52, why does such little current go upwards in the two diodes? The diodes won't be blocking the current in that direction.
2021 and still a great video! thanks!
that was fantastic, thank you, but I still don't know why my meter shows 44 AC volts on 120 Volts rectifier. Shouldn't there be only DC voltage?
Thanks
I would like to point out few mistakes:
(1:10) 1. Transformer do not convert AC to DC. It only steps up or downs the voltage of AC.
(3:25) 2. The diode isn't even connected to upper wire directly.
Conventions:
1. The current shown is conventional current.
How do I know?
In this diagram there is no wire running over another represented by an arc. But there are points where straight lines are connected.
The in diode, electron flows from backwards in this PN junction diode, whereas conventional current flows forward
electrons flow ---|-----------I>|------>----
This was great but why wouldn’t the current flow through the two middle diodes on its way back to the source when the current is moving clockwise? (Source to resistor direction)
Is it like a path of least resistance thing?
Also what is the component on the right?
Superb video. The only thing I'd have liked is for you to explain what's going on on the extreme right hand side (the stuff that's labelled 516μF. Is that bit necessary? If it is, perhaps you could explain why; if it's not, just say that it's not and mention what video in your series it's explained in.
Well done. Thank you so much.
Oh, and one other question whilst I'm here. These diagrams seem to be largely self explanatory but do you have a video to explain (for example) why we need to link a ground to the -ve terminal, and why the volts get labelled in increasing values as you go from -ve to +ve (since my intuition tells me that they should go in decreasing values as you move from the -ve to the +ve terminal).
Sorry to reply to my own comment, but I've just seen the video on capacitors which explains what's going on. It may just be worth while adding a comment to the video to refer people to the capacitor video!
I don't understand why the current won't flow in the forward path of the diode. In the return path of current, there are 3 diodes that are in the forward position according to the current direction. Although if the current flows through the other 2 diodes, they would meet with current that has not passed through the load yet. Any clear simple explanations? Thanks!
Thanks for the illustration
is it safe to say that this is what's installed inside of household LED bulbs?
this was a great explanation - makes it easy to remember
+sub ... greetings from Minnesota
What is the used Software in this video ?
And i need your recommendation to the best Electrical/Electronic Circuits simulation softwares you had used please 🙏🏼
Nice explanation, but it would have been nice to explain the role of the capacitor as well in turning it to flat line DC
At positive half cycle, current flows from phase(line) to neutral following the path from higher potential to lower. You put a voltage tester on line, it will beep, on neutral, it wont.
At negative half cycle the phase potential is lower than neutral so current flows in the other direction. So line becomes neutral and neutral becomes line.
But, do you mean that we have supply in neutral during negative half cycle? In this case, why a line tester would fail to glow if it is tested over neutral line at the negative half cycle.
Please explain.
Thank you so much! Wow thought Id never understand electronics
When the current switches to the second path, don’t the LED’s burn up because it’s now going through the resistor at the end and not the beginning of the flow?
I think it would be better to use the traditional diagram as in the thumbnail. The way you show it is a bit confusing to those learning. Otherwise I like your stuff. I’m subscribed. Even when I have seen people make a full wave bridge rectifier using four diodes by twisting the leads together they usually make the shape in the thumbnail.
Theres 2 diode on the return line in the same direction? How does the current know which line to go dow n there both connected to the same wire?
I'm confused or the electrons are moving in the same direction as the current? @SimplyElectronics
Even though the current has changed to a direct flow, that direct flow is not consistent, its slowing down everytime the ac changes direction so that DC is not maintaining a constant flow, its going fast then slowing down then fast again so the led's are going bright then dim then bright then dim, how do you prevent that dc current from slowing down ?? How do you make it a constant speed to keep the led lights bright all the time ?
You will need capacitor and voltage regulator
is it possible to filtrate dc voltage without using a capacitor in parrallel after the bridge rectifier if yes how ? thanks for your help .
Beautiful explanation 🙏🏻
Why do electrons flow through the diodes differently in this example than in your diode video?
Your channel is terrific! Thank you so much for your wonderful videos :D
Good demo, but I think that if you'd laid out the diodes in their typical diamond layout it would be easier for people to visualise.
What is this software for designing a circut?
everycircuit.com/
This is taken from his video on Diodes
Designing software is proteus
In one of the directions, electricity isn't flowing through the left-side diode, even though it's not blocking. I'm confused.
I'm also confused why he mentioned electricity wouldn't flow through the left-side diode going from top to bottom because there was no connection in the wires just above it
Best explanation out there,thank you so much.
I get the rectifier, but what I can't understand is what's happening when the electrons come out of the Leds. Why did it show then reversing on the right side of the screen? This is not mentioned or shown why. Send to me that the electrons on the right side should always be flowing in one direction. To the positive and out of the negative. What am I missing?
these tutorials are brilliant - thanks
Can i ask what application you are using for this video?
that is nice but why am I still getting some A C voltage past the rectifier?
Thank you.
When the diodes are faulty how would u bridge or bypass the diodes for the hair dryer to work
Amazing explanation. I only suggest to next videos, you could use a bigger white cursor instead this small black curso.
Thank you very much for the video,it helped me a lot 😀
Current flows from anode to cathode which is + to - , so the other 2 diodes were supposed to facing the other way am I correct
studying military weapons systems in ait thank you for your explanation
Understood! Thank you :) was wondering
thanks for a clear explanation, keep up the good work :)
What happened to the sin wave after it went through the resistor? Why did it disappear?
What program are you using to show your work?
thank you! this was very informative
do I use the same dropping 24v AC to 12v DC or do I need to go anouther route?, ev'ry one I've seen is dropping 110 -220 v AC down to a lower voltage, I'm only trying to run Leds, thnx
But one thing that I don't get is the second junction (the one left to the trio of LEDs); When electrons go, they're being forced to go through one direction by the diode, that's pretty clear. However that second junction (in purple) leads to two LEDs pointing THE SAME DIRECTION - so how do electrons know which track to take in order to complete the circuit? There's no diode on the way back forcing them to take any direction.
The top and bottom diodes only allow current to flow in 1 direction which is ---->
The 2 side by side diodes only allow the current to flow the other way
The capacitor is there to make the flow of current smoother? Did I understand that right?
got my subscribe loved the video, great content and explanantion. Thanks mannnn
Are there other names for recrifiers? Like AC/DC converter or some bridges maybe?
With what software have you done that simulation ?
What is that on the extreme left of the circuit?
Is EveryCircuit the software you're running to generate this schematic? Online or installed? Thanks!
The best explanation 👌🏻
Does this have any effect on the torque put on an induction generator? New if it wasn't already evident.
thanks a lot helping me...its goot project ...im verry int3resting in electronics....my love with u ..and..thanks sgain...with love...amd.
good explanation. can you make video like this with 3 phase ac to dc using 6 diode.
How does current flow through 0 volts line at the bottom?
Is it possible to keep all the negative polarity instead of positive after AC is rectified to DC ?
Is that all diode and led upside down? because refer to pervious lesson ... current/ electron flow through all this componets from negative side to positive , but here is from positive to negative, explain, thanks
finally, i get it.... current flow and electron flow are different direction
You are doing great 👏👏. Keep rocking
The video helped me so much!!
Hi there Simply Electronics)).
Could you (in one of your later videos) explain why there exist such things as 1,2,3-phases (in reference to motor windings)? And what's the difference between them? Thanks.
Yes, I can and will do a video on 3 phase power
Are you using conventional or electron theory flow in this circuit?
life would be easier if they told you , a new utube requirement?, never , but 'it does appear to be conventional current, positive to negative
@@kaycarolann As if to confuse an otherwise straightforward system so the engineer never knows quite how to read a circuit. Just asinine.
Can u show me how current will flow on hair dryer wiring diagram pls thanks
Wait, isn't current flowing in opposite direction from previous video ?
Whats the software he's using?
very nice explain bro, keep good work :)
Beautiful animation
What software are you using?
What software do you use to visualize these circuits?
Question the specification of the diode, i mean the voltage thats its can take, whats diode need to buy.?
You were right, it did look more complicated than it is.
Quality vid thanks brother
You did not explain the portion where the capacitor is located in the circuit. The movement of current there is in that loop looks strange to me.
Thank you very much for this video but please make your mouse cursor easier to see as it's very hard to spot.
As a novice in electronics, I wonder what purposes do the unlit diodes serve? I know what resistors, capacitors, transistors and few others do, but I am puzzled about plain diodes. 😶
Shovan Saha thank you very much for the information. 🙂🙂🙂
I thought the flow was from cathode to anode, like the video about the simple diode. I am confused
