1. The one who talk about this video
2. The "Great video" dude
3. *FFFFFFFOOOOOOOOOOOOOL* bridge rectifier
7 years ago, and still one of the best videos of it's kind on this site.
1 year late but I finally get an idea how a full bridge rectifier were supposed to work
*FULL BRIDGE RECTIFIER* , It's not a puny single diod- wait.. wrong channel
Ah, i see you are a man of culture as well
LOL coming from Electroboom
you prolly dont care but does any of you know of a way to log back into an Instagram account..?
I somehow forgot my password. I love any tricks you can offer me.
@Ryan Winston Instablaster =)
@Genesis Bradley Thanks for your reply. I got to the site thru google and Im trying it out now.
Takes a while so I will reply here later with my results.
Great Video! I wish my teachers back in the school days had been so clear about how electronics works!
great scott :bridge rectifier
ElectroBOOM : FFFFFFFFFOOOOOOOOOOOOOOOOOLLL BRIDGE RECTIFIRE
FUULLL BRIDGE RECTIFIER

I just began playing with electronics and these basics videos are a godsend! Thank you so much for making them. They helped me identify what I needed to know on datasheets numerous times!
Great video and it goes hand in hand with the labs I've been taking for my engineering courses!
Extremely interesting introduction to diodes and rectifiers.Well done!
One of the best videos about how it work a rectifier... Genial!
Please keep making basic videos like this. I am a beginner, and I have problems following most of your other videos, even the electronics basics playlist.
u r good in explaining the stuff
good videos are here to last!
Thank you for making everything so easy to follow and understand!
Now I finally understand how a bridge rectifier works!
*FULL BRIDGE RECTIFIER
Great video very clear informative! Keep up the good work
Great work. Nice tutorial. Keep up the good work.
I dunno what it is, but the diamond pattern is way easier for me to see. -- It just seems simple. -- Yours was kind of complicated for me this time around; if I didn't already know what a bridge rectifier was, I'd be super confused... anyway -- thanks for posting this. Don't be disheartened that I said this, I still think your videos are awesome. Keep up the good work! :)
You're a genius fella, thanks for the great video buddy
Awesome Video Dude. Keep up the great work. Nick.
The simplified wheatstone bridge was really well explained!
Dude! You're awesome
Thank u for such great videos
You make it easy to understand
Thanks For Making This Video ❤️
Excellently explained, young man!
Bent Hestad who says he is young
A MASSIVE ONE
surely i like it
ich finde du machst sehr gute videos. weiter so :D
Would just like to say that your video's are soo helpful and very explanatory in such a simple way!!!! kudos to you brother and keep up the great work!!! :D
Thanks mate
Love Your Videos
Great and fun explanation
Excellent! Tracing the current in the schematic is mega....
Hi Scott!
Thank you for the great video!
If you don't mind, please add a link to the transformer's product page - mentioned on 2:35.
Thanks!
you are the boss of electronic
Scott,thank you. Fine presentation like always.
Nice FUOOOLL BRIDJE RUCTIFIAAAAAA!!!
+Greatscott! just wanted to say I really like your videos and if you still doing Basics videos can you please consider doing one on diode clippers? Thanks!
Great video! i was able to understand, maybe you could've explained why current only flows in one direction?
awesome explanation :)
GreatScott!
AC-DC !!! Yeah !!! Great video as always ;)
You are really great
your videos are great but you have to add some fun to it
Full BRIGE RECTIFIER
Electro Boom!
you are really great
FULLLLL BRIDGE RECTIFIAHHHH
thanks for sharing,, by the way can you add the draw of simple schematic diagram of the circuit you used to convert the AC to DC completely. thanks a lot
Big fan...sir.
Thanks Scot
A MASSIVE ONE!👌
Hi, I just want to ask a question to you that , can we run DC motors of different input voltage ratings with a single motor driver circuit considering in mind the maximum supply voltage the driver circuit gives which in turn will be used as a information to use the variety of DC motor that can be used to run .
Great basic video, keep these low level vids coming!
Since an LED is a diode would it be possible to make a bridge rectifier out of only LEDs?
parley Kelsch yes you can. But only for 20mah...
yes
Yeah. Although for one that can handle reasonable current you're gonna want one of those beefy LED chips. It would also probably blind you haha
Aaron Niehaus And have a 36 volt drop across it lol xD
That's amazing
A FULL BRIDGE RECTIFIER!!!!! @elektroboom
dude this is like a zillion times better than engineering class (im a senior)
hi, greatscott, i have a dual usb power bank, it uses 6, 18650 batteries, on the board there is a component, its code is SBR2045CTFP, the problem is, when i connect two spartphones on it this particular component gets very hot, also, the batteries go low by a very short time, i presume its because power are getting wasted as heat, by what i understand of electronics, i believe that soldering a second SBR2045CTFP, cathode to cathode, and anodes to anodes, i can avoid the heating by, I BELIEVE, excessive current, is this correct? can i solder a second SBR2045CTFP in parallel? and this will solve the overheating? like so much your videos!!
if we place 2 diodes one reverse and one forward biased parallel in wire in rectifier it gonna work good??plz tell
and what rated doide do i use meaning do i go for a battery rated doide or the solar panel rated doide when i trying to charge a battery?
hey Scott I am going to be starting to do a little electronic tinkering can you send me the right way on what I should need
I FUCKING LOVE YOUR VIDEOS !!!!! IM A HUGE ELECTRONICS FAN!!!
wow soo usefull
hey great scott,i made a bridge rectifire at home but when i connected it to the mains it shorted and a huge spark appered.Plz help me how to make it and which diode i should use and is 220volts A.C too high for the circuit. plz reply
i already make full bridge rectifier circuit, but the output is same with half bridge.
Any suggestion?
I am modifying a popcorn popper for roasting coffee. I have disconnected the DC which has a bridge rectifier on it and connected a 26 volt transformer to power it. The transformer worked great to power the fan but after 10 minutes it got too hot I think and broke. How can I solve this? Why are my transformers not working more than 10 minutes? Is it because the load of moving the beans around is too much for the fan causing the transformer to work too hard?
God bless you Sir and bless Germany
awesome
hey good prooject. i have a doubt, does the rf transmitter transmit any voltage? can i add a diode there because i want to connect many encoders ht12e to i single rf transmitter , so can i use a diode there. pls can u reply me soon. thank u
Where do you get your perf board from? In my research the biggest size was about 200 x 100 mm. :(
Hi Scott, could you explain why the max voltage increases from 24.8V to 25.2V as you connect the cap at 3:36? Thanks, Love your videos!
looks like it doesn't actually change (visually, the line is in the same position as the peaks). this is just an artifact of how the scope is measuring the maximum voltage. it might do better if he changed the timebase to get more periods on the screen.
Would a smaller capacitor keep the waveform longer? I AM getting a cheap 500khZ toy scope to play with.
please make video about other types
there is a videio make a swith mode power supply (smps) circuit
2:23 or maybe you can get a FOOOOOOOOL BRIDGE RECTIFAIAH
Does a diode also have positive and negative
Hey Scott :) what's the program called you're using on minute 4:00? Than you, love your videos!

Full bridge rectifierrrrrrtttt. Electro boom
Do you have a video explaining how to make the circuit board at 0:43?
Thanks!

Great, informative video as always! :)
Small question: What is the music from 04:14 on called? :)
It's called "Home Stretch" and you can find it in the CZcams Audio library.
@@greatscottlab i love u and your video can i know your nationality ?

is the breakdown voltage a bit technical?
That feeling when you want to comment Full Bridge Rectifier and you realize you are not the first one with this idea😂😂😂
does 1N4007 daiods work to convert AC to DC
Thanks!
Thanks for the support :-)
you can not build the framework clock to two device?
I thank thee
how do i know what kind of one way doide to use?
Bridge rectifier are not always bad sometimes they are useful
FULL BRIDGE
Danke!
Thanks for the support :-)
ElectroBOOM will love this
I will get recommendation after 6 years
What's the song at the end?
I think I just generally don't understand how electricity works :,D why does it not flow through the circuit when the ground is on the diode and the 5v is on the other end? Does that mean you could put the diode anywhere is the circuit and it would always be okay? Thanks, great video :) I'm doing electronics for AS and really finding some part difficult to understand :L
All diodes have a certain (large) voltage where they will break down and let current through in the opposite direction than the one they're usually used for. Appropriately, this is called the "breakdown voltage". The reason diodes normally conduct electricity in only one direction has to do with semiconductor physics and the chemistry of their composition - basically, gaps in the atomic structure make electrical flow much easier in one direction (by design.)
Keep in mind also that there are current ratings for every component, so there's no guarantee that a diode would always be okay in either configuration!
What is a “flat” bridged rectifier?
Foooool bridge RECTIFIAAAAA
I have a toroidal transformer that delivers 28 volts ac, but after rectifying it delivers 40 volts! Why is that happening? It does not drop with the load.

Before you want to criticize, learn some sense of humor. How naive it is to believe that there is anyone who would spell the f word wrong? There is a thing called "Exaggeration", google it, please.

FULL BRIDGE RECTIFIER
Using a MOSFET is a more efficient way to protect from reverse polarity.
+DigGil3 Correct.
Thank you, Senpai, for noticing me!
+DigGil3 Haha no problem ;-)
Bartosz Olszewski I don't think so. Fuses are good for overvoltage only. In a reverse voltage they can allow it without tripping.
Bartosz Olszewski What kind of fuse is that?! Not of this kind, I'm sure: www.pssl.com/images/ProdImage01/1500/Z-FUSE-GMA-5A.jpg
Just multiply your RMS x 1.414 gives your total 👍👍👍 what you could cover is a equation in A/C house wiring ( fusing factor over load ) 👍👍👍👍👍
Would a larger diode typicaly have a higher voltage drop? And higher capacity?
So to minimize voltage drop i would use the smallest diode that i can?
Dang i wish i had a perfect diode :P
germanium signal diodes have a small voltage drop, but they will die with a few milliamps of current flowing through them
