Years ago, my sisters 1 yr old TV just stopped working "for no good reason". Sure enough, a careful look noted a suspect capacitor "bulging" at the top (that is why they have that scored x in the metal, so that it doesnt become a projectile). Went to Radio Shack, spent a $1.50 on an equal value capacitor, soldered to PC board and bingo, worked. Longest part of job was tackling the 57 screws to get the panel off / on. Good info here, thank you!
Would an aftermarket capacitor always work, as long as it is of equal value? Are there some compromises that cannot be made, e.g. capacitor type must be the same? I just fear that something "proprietary" might be on appliance capacitors and they may not be replaceable with off-the-shelf parts
@@re.liable Id hate to say 100% yes, but I can't see why not as long as the values match, even the materials shouldn't matter ie ceramic, metal, etc. Good luck!
I'm studying electronics at university, it's quite interesting, but there are no practical works. This channel is a nice solution for that. I have learned a lot. Thanks! :)
Outstanding training video on Capacitors. Best I have ever seen! And certainly a lot clearer and more useful than the info I learned in EE class years ago. Very well done - and - thanks !!!

Just wanted to ask. Are these good quality capacitor brands? ,Murata ,KEMET ,AVX ,Vishay. im starting to do more SMD stuff and i dont know which brands are good or bad and prices go up and down all the time so that dont help
Respekt, du machst echt super Videos. Ich schaue mir deine Videos schon länger an und muss dich echt loben. Du hast auch dafür gesorgt, dass ich ein riesiger Arduino-Fan bin.
I remember going down to my local scrapyard and picking up a load of old electronics from their "breaker" skip, there were TVs, Radios, Games consoles (Handheld and full system), even some PCs! Tested them all and most of them didn't turn on, checked the caps and realized the majority were blown, swapped them out and ended up with almost £3000 worth of working electronics for their scrap price! (About £60!)
Great video, as all of these "basics" videos from you are =) Really like them! I do like your other videos as well of course =) However, if you haven't planned for it, how about a video on Mosfets? I can't remember anything back from school about them, and I hardly have any knowledge of them so I thought maybe you could do another excellent video with that as subject? Would be cool! =) Keep up the great work!
Great stuff. One small correction on 2:09: The more capacitance and greater maximum voltage rating a capacitor gets, the more energy (not power, which is energy divided by time) it can deliver.
hello, i just started studying electronics for 2 months now hh only basics, and i have one simple question it may seem obvious for you guys but for me as a beginner things are still sometimes vague for me, my question is: Why would Capacitors be destroyed when you reverse their polarity, since they can also be used in AC current? as it is known that in AC, Current switches its direction through time, and thank you so much for help.
got a huge tv, broken of course from my father, took it apart, replaced 1 capacitor.. and now i have a huge tv!, a huge improvement from my b/w crt tv, i always tell this story, but this time i at least have the context of this video to go with it. never throw something in the trash without attempting to repair it!
Hey GreatScott!, I recently subbed because I'm a programmer who is interested in learning about the hardware end of things, and of all the electronic channels I've found, I really enjoy yours the most! I admire your knowledge on the subject, and want to learn as much as I can! I have yet to start any project with electronics, so I don't want to foolishly pick a project too difficult for me. If that happened, I think I'd become easily discouraged. To avoid this, I was hoping you could recommend simple projects that are good for learning the usage/applications of all of the components you've covered in your Electronic Basic series (resistors, inductors, capacitors, etc)! Thanks, and I look forward to seeing more, awesome videos!
Awesome video. Better that most I've seen because of the real life examples on how to build one and capacitive reactance and so on. Keep up the good work. Cheers :)
these videos are way more well filmes and understandable, last but not least more professional then many others on the same topic out there! Even if you sound a lil bit german XD
Would be cool if you showed more how you set up your circuits. You always just show some wires and stuff clamped together and then some oscillator, multimeter or supply output. How do you set up these examples, what sizes of the components are you using and why would really help.
I found it best to visualise a capacitor as a reservoir holding back the water flow from a small stream. When held back, the flow accumulates within the capacitor and when released it has more force; the force of a faster river.
That makes a little sense, but it wouldn't be constant in that case. when it's releasing, the small river couldn't keep the reservoir filled. so is there like a reset or something? or something that triggers the release?
Landon Rivers when the metal plates are connected to the battery, one battery terminal takes electrons from one plate and the other terminal pushes electrons onto the other plate. so now one plate has many extra electrons and the other has an electron depletion. remember it's only the electrons (negative) that move and only in conductors (which is why they're conductors). The protons (positive) don't move. If you disconnect the battery the electrons have nowhere to go so they stay. like putting your finger over a balloon hole, no air can escape even if it wants to. because of the amount of electons on the plate, due to the size, it causes an electric field. what happens when you put two magnets of the same polarity together. They repel. simular here. All those negative electrons that were forced togethe in a plate want to repel. The centre of the plates is insulated. no electrons pass. but the field can bend the electrons on the insultor and this creates more space for storage. I'm no expert but I think I got it most right and I hope it helps
When explaining charges, you should probably explain with electron flow (negative to positive), not conventional current (positive to negative). Makes more sense.
I made my own capacitor from 2 sheets of aluminimium foil separated by cling wrap. I folded it all up into a cube and taped it. I actually got 500nf out of it. But it leaked all of its charge very quickly. Rimstar has videos on making caps, dry andelectrolytic. I should make one of those some time.
This may be a vague question, but... Do you know what would be the average capacitance for a polarized capacitor, that can hold 20 kilovolts? Or if there is a method to finding the normal capacitance to keep something going for about 2 seconds?
For those who would like a tiny analogy: The absolute best analogy for capacitors and resistors is a mass-spring system. Voltage would be force, velocity is current, inductor is Mass, capacitor is a spring, and resistance is friction. instruct.math.lsa.umich.edu/lecturedemos/ma216/docs/3_4/spring.png Trust me the equations are Identical to a rlc circuit.
I repaired 3 monitors replacing the blown caps. In the store they declared me to be crazy. I was't the only problem. Just got the same F rating and replaced them with higher voltage versions in my case i put in some panasonic caps. And 5 years after the repair i still use this lcd monitor (made by samsung). I think they use bad component's on purpose. With higher grade caps it ran 5 years for now after repair. While they ran 2 or 3 years after purchase. Two same lcd had same issue bought the caps for both while one gave up after 2 years. I'm like 6 euro for all the caps. I'm not going to take a risk on the second monitor. One of them has a bad line in the display ( after 5 years of total use) non repairable. And repaired a hp monitor the same way. One advice buying a monitor. Buy it without a power supply into it. So you can manual replace it without any issue.
I've repaired 5 monitors, 1 radio, and 2 Pentium 4 motherboards. And yet have to find out if it works for power supplies. Just be sure you're checking the heat rating when buying new caps, I had to replace the caps on the first monitor, again, after not realizing cheaper means lower heat rating.
Yeah the heat rating. That can screw you over. Pretty bad. Especially on monitors as they have no active fans. Just pay the price for caps and we are talking like 6 to 12 euro/dollars per monitor.. They should be better then the once inside. And for the temp rating there was no reference on the ones in the old monitors so i took the ones with the highest value available at store. Also check the size. Had to run a wire for one cap as it didn't fit otherwise. No problem for me but could be a issue.
killerbeenl The need to run a wire shouldn't be an issue as long as the cap is in a location that isn't any warmer that the location on the board, and the wire can handle the load. I can't remember what I payed for mine, but I believe that my first monitor's first round of recapping cost me under 5 USD, and the second round was double that. I believe it applies to anything you fix that is over 10 years old, a re-cap and resistor replacement usually solves the problem.
Would be a great addition to hear your thoughts on testing capacitors (without the expensive capacitor tester you have) both in and out of circuits. Such as with ohm meters (out of circuit) and I only just learned of ESR testers, which I think can test in circuit though I am still not sure how they work, can’t figure out how they isolate the cap from parallel components in circuit.
My issue is a little off topic we build custom motorcycles and the bigger the motor the motor starin that is put on the batteries even if high CCAs. So what we are thinking about doing is adding a capacitor to give the battery a boost during starting. I have been watch all sorts of youtube videos on this and people are using anyware from 14v-50v capacitors. From my understanding is the voltage doesn't matter since that is just a maximum voltage the unit can handle and with heat and age that maximum voltage rating can drop causing the capacitor to burn out. So we are planning to use a capacitor at least 3x the bikes voltage which is about 13.8. But what we are most concerned about is the farad rating. I watch an HVAC companies video on capacitors and they say that too large of one can burn out their motors so they deal with microfarads instead. So we are wondering if this will be an issue with a motorcycle starter and other electronics that there is a certain farad rating we should stay below or not? I have see all sorts of capacitors for cars that ranged from 1 to 50 farads and more. I don't think we need anything that massive but we want something to give a good boost to the battery at start up so the bikes fire easier instead of lagging on the compression stroke with all the lights fading looking like the battery might not have enough oomf. Can you advise a capacitor rating? Since they will need to be small enough to hide on a motorcycle we will most likely just have to order basic capacitors from overseas and what not to wire ourselves compared to one of the large stereo units that comes complete ready to bolt in and connect the wires. Any help would be appreciated. Thanks,
Hi, Scott, it is a very nice capacitor introduction video. I like it. a question, how do you measure current with oscilloscope in another channel, i guess you measure the voltage on a resistor in series of the circuit, right?
electrolytic are mostly polarized, high farad level, low voltage. some ceramic ones are high voltage, low farad level, and mostly unpolarized. but dont mix up ceramic capacitors for tantalum
Both sides get charged, not just the negative side. One loses electrons the other gains some. The component as a hole stays uncharged, same number of total electrons
Watching that capacitor burst half way through the video was really satisfying. I tried to achieve that a few weeks ago by reversing the polarity with a 9v but nothing happened. Can someone shed some light?
Good video ;) I have a idea for the next video Electrical Resonance (I know already what electrical resonance is, but a lot of people don't, so maybe you can explain them what it is) Alex
Since you talked about a monitor/tv... I was just wondering if you might know whats the cause of the following issue with my granddads philips lcd TV... When switching it on, the image is upside/down, mirrorred around and the colours are similar to photograph negatives... after a while, about 15 minutes or so, it flips and works great... Shut it down and power it right back up and the image is still fine, but let it cool down and its the same thing over again...
Instructive video of a good serial! For a project I need to provide a pulse of 95 mA for 100 milliseconds @ 12VDC to open/close a latching solenoid valve. I was thinking of a capacitor with a BJT as a switch controlling the base from an MCU. Could it work?
Hi your videos are awesome (specialy the LCD Cube) Could you some day make a video about Chips (555 Timers, Eproms etc)? As I would love to know what is inside them Thanks and Best Regards
Hi Dear. I like ur way to guide people. can u tell us where to download pc software for electronics design.the software which we can design a circuit and test it on computer without physical testing.

Watching that capacitor burst half way through the video was really satisfying. I tried to achieve that a few weeks ago by reversing the polarity with a 9v but nothing happened. Can someone shed some light?
Try a bigger voltage
Try a bigger voltage
I should note theyre electrolytic caps rated for 25v
Well you are under the max voltage. Try joining 4 9v batteries, that could work
wonder of Capacitor ! Nice tutor.
U r the best bro!!
Your videos r great
🙏💓nice teach sirji 💓🙏
Thank you so much, well explained....
Good video ;)
I have a idea for the next video Electrical Resonance (I know already what electrical resonance is, but a lot of people don't, so maybe you can explain them what it is)

High Voltage I put it on my to do list.
GreatScott! Awesome :)
Awesome i learn so much from you ;)
Since you talked about a monitor/tv... I was just wondering if you might know whats the cause of the following issue with my granddads philips lcd TV...
When switching it on, the image is upside/down, mirrorred around and the colours are similar to photograph negatives... after a while, about 15 minutes or so, it flips and works great...
Shut it down and power it right back up and the image is still fine, but let it cool down and its the same thing over again...
Great Video
3:48 - a mushroom? xD That is a nice video! Keep doing videos like that!
Instructive video of a good serial! For a project I need to provide a pulse of 95 mA for 100 milliseconds @ 12VDC to open/close a latching solenoid valve. I was thinking of a capacitor with a BJT as a switch controlling the base from an MCU. Could it work?
Thank u.i need more explanation
Hi your videos are awesome (specialy the LCD Cube)
Could you some day make a video about Chips (555 Timers, Eproms etc)? As I would love to know what is inside them
Thanks and Best Regards
Veso266 I put it on my to do list.
Hi
Dear.
I like ur way to guide people.
can u tell us where to download pc software for electronics design.the software which we can design a circuit and test it on computer without physical testing.
+GreatScott! Please reverse the order of the videos in the playlists. Make the most recent the last. So that we can watch them in order, not reverse.
great intro
Its good for me .I like it because i prefer the electronic work
can you do a favor for me
plz give me a video about HOW TO USE MULTIMETER plz plz
Would you explain voltage ratings of capacitors too please.
