I GRADUATED FROM THE CLEVLAND INSTITUTE OF ELECTRONIC BACK IN 1984 AND HAVE PLAYED WITH ELECTRONICS FOR OVER THIRTY YEARS YOUR EXPLAINATION ON CAPACITORS IS FAR AND AWAY THE BEST A HAVE EVER SEEN. IREALL LIKE THE BLADDER EXSAMPLE REALLY GOOD JOB THANKS
Outstanding videos! I'm still looking forward to your video on inductors. You mentioned that you would be putting one together next, but that was over a year ago. Just a reminder that your viewers are still interested.
Glad to hear about safely discharging super capacitors, I work in the service industry and discharging caps is always dangerous. Your detailed videos are great. Thank you!
I do not know how I could have missed your channel as I am self taught in electronics and you have one of the best channels I found for learning really GREAT - now with you bigclive , Mr Carlson's Lab along with ElectroBOOM just to name a few that I watch on a regular basis I should be ALL set!!! Thanks for taking the time and effort to make and post these Great Videos Sir Two Thumbs Up!!!
I'm using your videos to supplement my community college classes. I'm preparing to work in the electronics field and your videos have been invaluable in providing me confidence from understanding the material.
I think this electronics tutorial is great! I love how you take everything step by step and give so many examples of how it all works. With the detailed explanations, the water system analogies and then the physical demonstrations, it really helps to drill the concepts into your head. Any plans on coming back to this series? I'm really bummed that it's been 2 years since we've received a proper update.
Love our Nissan Leaf EV - and I can already imagine the great benefits of new capacitor tech to replace batteries - that will be a game changer with regards to EVs and basically anything we can run from batteries today!
Your explanations are so clear that I subscribed and look forward to all you put out. I plan on returning to a "tech school" soon with a goal of designing, altering, and then building simple circuits. I have a passion to create effect pedals for musical instruments. Thanks for what you are doing, it is awesome!
Excellent quality tutorial! Thanks mjlorton for your contributions. They are certainly very helpful for people like me who are searching and thirsting for knowledge of this kind.
Beautifull! Great tutorial, i'm definitely gonna save in the favorites. Its great to revisit and rethink the basics. You pretty much covered all i know. the only additional thing you could possibly add is, typical range of capacitance for different capacitors, like, ceramic, polyester, etc....
Was there ever a #10 made ? Moving on to inductors and full RLC's etc? Great tutorials and analogies, makes it very clear. Analogue always drove me nuts, digital is so much easier to work with. You are making Analogue easy to understand.
Martin, I must say these videos are great source of learning about electronics. Greatly appreciate for your efforts. I was looking next video in this series for other components but not find those other than 555 timer 3 videos. Kindly share if any other videos exist in this series after #9. Thanks
Thanks...So that sums up all the variables, math formulas, different circuitry applications and behaviour, testing, fault finding, safety, and general practical uses examples... would love to see a video of a more complicated circuit performing a task with them... Capacitors - Part 3?...
An important characteristic you left out is temperature stability, how a cap's value changes with temperature. Some ceramic disc caps have very poor temp stability for example. Also, testing for leakage at rated voltage is very important for high voltage caps in high energy circuits, and this is something that now only very expensive lab testers or older vintage testers do. The modern cap testers and LCR bridges you have mentioned/reviewed will not.

Very interesting info about super-capacitors at the end of this video!... I too look forward to what the industry does with those in the future, especially in portable devices, cordless tools, and vehicles! Awesome test equipment setup you have there too!... I wish I could afford all of those fancy meters and scopes and such, but all I've ever been able to buy is a very basic and simple, handheld multimeter. I really wish I could get a very good and accurate LCR and ESR meter, and of course an oscilloscope would be awesomely handy to have also, but unfortunately those luxuries will probably never be realistically within my budget. :(
Hello Martin, I've watched your tutorials for beginners, from 0 to 9, and I've learned a lot. You are an excellent presenter. However, I thought the tutorials would lead to simple circuits for beginners. What do suggest I look at next, after watching Electronics Tutorial #9 - Capacitors - Part 2
thank you very much for your nice video ,my question is for how long or how many hours a campacitor can stay alive or incharge after taking it out of a microwave or a dishwasher or anything else?
I listened to tutorials 1-9 and they've all been great. Is #9 your last tutorial? I see there are a lot of other videos on your site. What do you suggest would be the next logical set of videos to watch?
i am having the time of my life trying to figure out this whole oscilloscope function generator grounding issue, its like those two tools are useless when paired...and i dont have another floating scope lying around , guess ill have to stock up on transformers
May I suggest a tutorial about the cables, gauges, types, resistance, uses, endings (I know you did a tutorial how to crimp etc but looking for more on standards used). It would be great as I am a beginner and I find it hard to chose what cable to use for my needs weather for car, home 220V or for 5V Arduino projects. I already have Sparkfun Arduino Kit and I am going to start with it next week but I worry what to get for future.
I thought the AC impedance or capacitive reactance of a capacitor has an inverse relation to the frequency. @ 7:30 you said increasing the frequency increases the impedance of the capacitor. Am I misunderstanding something? Thanks.
Hi sir, I have a doubt at the time 17:04, you have mentioned that HF noise ( AC ) can be grounded by adding smaller capacitor. But only one side connected to circuit and other end is connected to ground. As per the analysis, one side of AC voltage going to charge the capacitor, how it will help grounding the voltage to reduce the noise. May be basic question? Thanks.
+sri ram Hi, it is a standard method used commonly in circuit design. Remember the equation ( I=C. dv/dt), this equation underpins capacitor function, it says that current only flows when voltage changes with time. AC is a change in voltage over time, therefore you have a short-circuit to ground. A DC signal is constant, it DOES NOT change with time, therefore a capacitor appears as infinite resistor (aka open circuit), and dc current does not flow.
I couldn't grab hold on the information as in your previous videos. That is obviously because of the difficulty the video has relative to the others. Though I don't quite get how all these hard calculation could help me get started with circuits. As you showed in previous videos, use of a capacitor to smooth the wave coming from the rectifier seemed rather easy to me. This however should be more my concern than yours. The video was as always really good, though it overcomes the series level of difficulty, according to me.
I am very thankfull for these videos. On a constructive note. Inductance wasn't really introduced very thoroughly before you started talking about it. I not sure if it has something to do with current induced through magnatisum or what?
it has something to do with filtering ability of the capacitor,higher esr have lesser ability to filter ac signal,higher frequency noise.(not sure,correct me if i'm wrong)
Sir, what you explained ow some, Thanks you, If possible also explain how to use 220 volts and 440 volts capacitor in the circuit with example. Thank you.
Martin, for some reason, i could not get esr usage.. what is the effect of ESR increase or decrease to capacitor.. i could not find this detailed in part 1 or 2, pls advise. what does ESR have anything to do with capacitor
My question is If we conect 6 capacitors in series (2.7V 10F) can we use voltage 6 x 2.7 = 16.2 voltage during the charging process? I would charge the capacitor using PV panel (12V 1.2A) and then run using the accumulated charge electromagnet with power 24W (12V 2A) for a fraction of a second. is it possible?
I am an old fart, back in the 70's I tried taking a correspondence course on this stuff but life got in the way. After the first video, my brain hurt... But the second one put it all in order and eased the brain pain.
You might want to take a look into what "Lazerhacker" is doing with capacitors and solar panels, etc. He has a page on youtube. If you both put your heads together you might do some really interesting things.

I have finished all the tutorials up to capacitors parts two. I would like to know if you have more tutorials so as to keep on learning.
Amazing help thanks but where's part10? This series of videos has helped a huge amount :)
watched this whole series gained so much...!!
really apprectiate your good work n your great tutor :)
moving ahead to arduino now (Y)
My pleasure, thanks for the feedback.
Another great video tutorial. I keep learning "stuff" about electronics by watching your videos. You sure are an interesting mate. :-)
Excellent video. Can you please elaborate more on ESR? How does it effect the capacitor performance? Can you show us some ESR measurements?
I listened to tutorials 1-9 and they've all been great. Is #9 your last tutorial? I see there are a lot of other videos on your site. What do you suggest would be the next logical set of videos to watch?
I would like to know the answer to the same question
Thank you for this series.
Where/when #10 inductors? I have never been able to understand them but I think the
wonderful way you explain things I finally will.
i am having the time of my life trying to figure out this whole oscilloscope function generator grounding issue, its like those two tools are useless when paired...and i dont have another floating scope lying around , guess ill have to stock up on transformers
Thank you very much this was extremely helpful

Another good video. Appreciate it.
+mjlorton What is "charge," or 'Q' exactly? Is it the density of charge or electrons between 2 plates? Is it mathematically comparable to AH or mAH?
Just curious if you have posted a page with all these formulas you use in your tutorial videos?
another excellent video. Thanks

Sir,
what you explained ow some, Thanks you,
If possible also explain how to use 220 volts and 440 volts capacitor in the circuit with example.
Thank you.
Do supercapacitors come only in low voltage and high capacity? Or are there any that also work with high voltage? Thanks...
Heavy going but very informative and excellent teaching, thanks,
Hi were is the e on the Ti-30xs [1-1/e] Thanks
Hello, How do I calculate the ESR of series connected capacitors ?
awesome tutorial...thank you x 10000000......
Excellent. Thank you.
Another good video

Martin, for some reason, i could not get esr usage.. what is the effect of ESR increase or decrease to capacitor.. i could not find this detailed in part 1 or 2, pls advise. what does ESR have anything to do with capacitor
Hi thanks for the reply,,keep getting error,,can you show me the whole formula for [1-1/e]
as i am doing something wrong
MJLORTON , U r gr8 :)) Keep it Up
i might have found a career path thanks your videos it looks interesting
Can u make one on Transistors?
Hi please make a video on discharging of capacitors
Tutorial #10 please
Will there be a next episode in the series coming out?
My question is
If we conect 6 capacitors in series (2.7V 10F) can we use voltage 6 x 2.7 = 16.2 voltage during the charging process?
I would charge the capacitor using PV panel (12V 1.2A) and then run using the accumulated charge electromagnet with power 24W (12V 2A) for a fraction of a second. is it possible?

Awesome video. Thank you.
Is this the last video in your series on electronics?
two thumbs up... great video...
My pleasure, thanks for the post.
hi i want to buy an osciloscope, which is better analog or digital, thanks
Great video thanks
Thanks very helpful video
Please upload new lessons. Its very helpful, Please try to do some experiment for demostrations. Please Please... I like the way you teach. Please
Dankie MJ!
Great Work
why when i type this into a calculator do i get syntax error? any ideas?
At about 28:00 you are actually talking about kers used in formula 1 cars...
Thank you so much!
21:10 Operatial, funny I would never have spotted that typo if you hadn't pointed it out!
Nice explanation but I'd be keeping a safety wire on those big caps.
Are you going to do inductors like you promised or what?
