Hey Nick, would you please make a video on how to test amplifier Transistors in circuit with a multimeter for newbies? How to identify the pairs, how to identify the pins, how to compare a good channel to a bad channel, which supporting resistors and diodes to routinely check if you find a bad one, etc, etc. I'm sure many would find this extremely useful. Love your videos and the way you explain things. Many thanks.
Excellent practical demonstration brother ...keep it up...you explained better than my college teachers👍👍...do keep putting such informative practical videos.
Your videos are incredibly easy to understand and your voice is relaxing to listen to. Great great stuff. One question, I noticed that your repair videos you almost all the time find the problem and achieve a successful repair. Does that mean you are always able to repair pretty much anything thrown at you, or do you just not publish videos where the repair was not possible? Thanks again and I have subscribed to your channel!
Nobody has any questions? I have some. I've been searching for info on how to restore and/or improve the electrical components in a solid state Crown D-150 amplifier and possibly doing a recap on my Pioneer SX-580. In searching for the parts of the latter project I came across the Ripple Current stats. Which brings me to my questions. What should I look for when it comes to Ripple Current? Is there a better balance/formula for selecting capacitors than what the engineers came up with for the design? How far can I take it with these projects before I need fancy equipment beyond a multi-meter? I have more questions. But I'll leave these for now. It's helpful to actually see how the signal acts applying the different uF to the circuit. Great video, thank you!
Only thing I would add is that I would call this smoothing, not filtering. But it does work saying "filtering the ripple" sure, I'm just more comfortable with "smoothing the voltage" so there is little to no ripple. I would use "filter" word for , say, filtering the noise, as in removing the noise, letting clean signal pass .
Could you give me some information about the last one. I got a step up DC to give 15v from 3.7 battery to my headamp, may I get some advices from you to make DC output more smoothly! Thanks!
Good explanation, got a 24v 75va transformer I want to smoothen dc output . Already have the bridge Rectifier, what size of capacitor do I need to remove ripple? I need to power supply for my diy 24vdc soldering iron.
I have to replace an audio filter capacitor with a rating of -- 50v 15,000uF. Can I use a, 65v 12,000uF capacitor in its place? What effect will this have on the circuit?
Nick, what happens if you insert all of the smaller capacitors into the breadboard? Is the output the result of all of them or just one of them, or what?
Why do we need to straighten up the current signal ? I have 2 power supply units taken out of 2 different computers. I wish to create 24v output from the two units by just taking each 12v output and join each pair of wires. Is this a correct way to get 24v output from the two power supply units ???
Unfortunately that will not work. The way to make 24V out of 12V is with a step up transformer or a DC to DC boost converter. You’re probably better off buying a new 24V power supply. You can find them for as cheap as $10 on Digi-Key
As long as the capacitor’s voltage rating is well above the supply voltage and the capacitance is sufficient for your application, the electrolytic will work for filtering (very low frequencies). To filter higher frequencies, you’ll want to use a capacitor with a much lower capacitance than what electrolytics can offer.
2 or 3 capacitors in parallel will certainly give you more capacitance than just 1, but unless more capacitance is required, 1 will do just fine. It all depends on the demand from the load.
If by input capacitor you mean in series with a signal, then it’s being used to block DC voltage and to only allow AC to pass. If you mean the capacitor runs from high to low, or from some voltage rail to ground, then it’s being used to smooth the voltage.

This video FINALLY made sense of capacitors as high pass filters in audio to me. Thank you so much!
how do you make sense of high pass filter from this video?
I've been searching for this video for a couple months! I found it the morning my oscilloscope comes in the mail. Haha! Thanks!
Thank you for taking the time to explain this, so thoroughly. I have struggled to understand how and why smoothing capacitors worked.
I love that you put the waveform in line with the circuit, way easier to visualize👍
Absolutely, lovely video. No explanation is complete without examples.
Great explanation and visual examples of the various capacitor’s filtering capabilities!
Been tryna figure this exact thing out for days now. Thanks man! A lot of help!!
Good stuff, Nick. Thank you very much! Off to your channel to look for advice on choosing equivalent caps for vintage equipment.
Thanks for an extremely easy understanding explanation with the examples shows in the video.
I think I was looking for this video for long time keep it up. Excellent videos
Great video, clear explanation, wondefully demonstrated. Thank you

Beautifully made video good sir. I bookmarked it.
Thank you very much, good simple-to-understand explanation! :)
The perfect and practical way to explain
Excellent practical demonstration brother ...keep it up...you explained better than my college teachers👍👍...do keep putting such informative practical videos.
Great explanation bro, you really made my concepts
Awesome demonstration
Hi, you were great and thank you so much for putting this out!!!!!
Great explanation. I was hung up until I saw this video because capacitors have a large impedance near DC.
Great explanation.
Excellent video.
Loved the video, thank you!!
Glad to hear it WRX BLK FLASH.

Nice demo sir
Awesome vid!! Thank you
Brilliant!👍
nice video, thank you.
Thanks for your video, excellent 👍, I
Awesome, thank you
Thank you very much.
excellent!!!
awesome works a lot
very helpful thankyouu sir
Thanks in a million
only i wonder, we see the difference without any load. İf we have any load how looks it?
Could you give me some information about the last one.
I got a step up DC to give 15v from 3.7 battery to my headamp, may I get some advices from you to make DC output more smoothly! Thanks!
thanks
But there is no load on the circuit, what happen when we put something on the circuit ?
Thank you, i love it . But if we are talking about Capacitor as Filter and Coupling , is that different ?
They are different. A coupling capacitor will be used in series with an AC signal to block DC.
Therefore, can it tame the square wave input and reduce the hum (undesirable ripples) on induction motors???
How big capacity should my capacitor have if i have 100V max AC from my wind turbi e going trough bridge rectifier
Thanks for simplifying it for this caveman.
After bridge rectifier if I add a two 35v 4700 capacitor will it give pure dc output and will it be safe to run dc appliances
l really learn something
Could this be used to smooth the Pulsed DC in modern automobile wiring? Please advise.
They make filter capacitors for car radio.
Good explanation, got a 24v 75va transformer I want to smoothen dc output . Already have the bridge Rectifier, what size of capacitor do I need to remove ripple? I need to power supply for my diy 24vdc soldering iron.
Why the who do you need a 24v iron for?
2200uf 50V or 3300uf 50v. Measure the AC at the output, if you still see add more capacitance in parallel
I have to replace an audio filter capacitor with a rating of -- 50v 15,000uF. Can I use a, 65v 12,000uF capacitor in its place? What effect will this have on the circuit?
Is ceramic capacitor good for AC to DC ripple filter?
Nick, what happens if you insert all of the smaller capacitors into the breadboard? Is the output the result of all of them or just one of them, or what?
If they’re connected in parallel, it would be like having one capacitor installed with a capacitance equal to the sum of all of the capacitors.
Why do we need to straighten up the current signal ?
I have 2 power supply units taken out of 2 different computers. I wish to create 24v output from the two units by just taking each 12v output and join each pair of wires.
Is this a correct way to get 24v output from the two power supply units ???

Can you use any electrolytic cap as a filter cap or does it have to be designed for filtering
As long as the capacitor’s voltage rating is well above the supply voltage and the capacitance is sufficient for your application, the electrolytic will work for filtering (very low frequencies). To filter higher frequencies, you’ll want to use a capacitor with a much lower capacitance than what electrolytics can offer.
Is it any better to use 1 farad capacitor also known as super capacitor?
That would be massive overkill!
what about using 2 or 3 caps to do the job. would that be better?
2 or 3 capacitors in parallel will certainly give you more capacitance than just 1, but unless more capacitance is required, 1 will do just fine. It all depends on the demand from the load.
الدوبي 😂♥️♥️
Y do we have a input capacitor?
If by input capacitor you mean in series with a signal, then it’s being used to block DC voltage and to only allow AC to pass. If you mean the capacitor runs from high to low, or from some voltage rail to ground, then it’s being used to smooth the voltage.
Yep i meant the cap in series
Thanks bro 🤘🏻
c16 for what... u dont explain
Filter capacitor filtering but how? That is I'm expecting from you
Could you give me some information about the last one.
I got a step up DC to give 15v from 3.7 battery to my headamp, may I get some advices from you to make DC output more smoothly! Thanks!
you can use step up converter such as xl6009
