Capacitors - A to Z of Electronics

[youfrancis]

These are EXCELLENT videos. :) Thank you for doing this.

[Wildcatbeer]

I had a cap blow off a motherboard next to my leg. Sounded like a gunshot and scared the hell out of me!

[ThedudeVip3r1990]

Thanks for this information beauty.

[ArcadeGames]

Your such a smart girl, why can't there be more girls like you?

[CKS5000]

I have two capacitors in my guitar amp and I tried to go online and find replacements but was unable to. youtu.be/jzgc2XjcuB8. will somebody watch this video and tell me if you know what kind of caps these are? You could also click my name and watch it on my channel.

[BarriosGroupie]

Looks like the eevblog has serious competition

[vincentstockdaletv]

Hi Jerry just was wondering if capacitors have a positive / negative side to them and if so how do I go about telling the two apart.

[tmfred1]

Of all the electronic components the capacitor is my favorite - it has so much potential. ;-)

[steelmesh]

Nice!! We recreated 2:00 in a HS Robotics Class 1998...20 students to their knees from a van-de-graaff, 20oz coke bottle, water, paperclip, and aluminum foil.

[iBradleyAllen]

hi i didnt understand the part about the disc, what was the setup? i didnt catch what was connected to what; that looked like a disc out of a hard drive?

[Development2112]

Well that was... Unexpected, fascinating/ nice.

[bewaretheintertubes]

Dude.... You restore my faith in humanity. Thank you.

[RavenRof]

Just found this channel and im amazed. Excelent work, thank you so much!

[Ryuuken24]

Damn, this is way too confusing, than it needs to be. Comic satire was okay, tho. Cheers!

[kinglonewolf104]

Thanks for the lessons in electronics. I love your normal videos, but the A To Z series is definately a must watch for anyone interested in electronics :)

[djaa2807]

Hot nerd :)

[Inshui]

LOVE IT!!!!!!!!!!!!!!! Now please do a video on mosfets and power transistors. (jk) ... you're helping me get unconfused about how this stuff works!

[mondalaci]

I was laughing my ass of when noticed the chip sound of the birds. I gotta watch this again! :)

[lewisleeming]

Thanks for the lesson.

[MrMultiSingularity]

hehe, we made capacitors in 6th grade using a paper clip, a film container (remember film? the stuff that goes in old cameras?), water, and aluminum foil. We charged it with a balloon.. hehe, fun times, fun times

[StevenErnest]

Maybe you could do a basic explanation of electricity sometime...? I understand it's the flow of electrons... but the number of electrons define the atom, so I guess as they flow, the number stays the same? It seems I read that when a circuit is broken the lightbulb, for example, goes on; it would seem it should be when the circuit is made... I dunno, lol.

I learned about you via your interview with Leo Laporte and Tom Merritt, and enjoy your vids.

[jeriellsworth]

@StevenErnest Check out my other videos and I'll be making more in this series about electronics.

[StevenErnest]

@jeriellsworth Cool, thanks! ^_^

[markiduval]

I see Game & Watch games in the background behind you! Awesome!! :D

[FlameAlpha]

awesome!

[sakuraness]

The video is so well done!

[beastlt12]

I Actually laughed when the second bird responded.

....'Cheap?'

Awesome 

[RobKohr]

@beastlt12 That was my favorite little bit too.

[ntomata0002]

You are hot and awesome!

[Kmezon2]

great video, thanks for uploading

[AmazGraz]

Wow. Did that led survive the 9v? It was pretty brief. Your puppetry is pretty charged up :^ D

[jeriellsworth]

@AmazGraz I'm not sure if it survived. It was something laying on my bench, so no big loss.

[kholt420]

Great video, J. My grandfather worked in an auto repair shop until he retired around 1980. Not only did he tinker with electrical and mechanical gadgets all the time, he was a great practical joker (great combination, that). One of his favorite gags was to charge up a capacitor from a car's ignition circuit (this was way before electronic ignition) then holding only the case to avoid closing the circuit he would toss it to someone else in the shop. They'd just catch it without thinking - POP!

[jeriellsworth]

@kholt420 We did this in our autoshop at school. :D

[alphabeets]

...so in the transfer of AC voltage through a cap, is magnetism essentially what is causing this to happen? That would seem interesting. Or is this "attraction and repulsion" different than magnetic attraction and repulsion? Can bringing a magnet close to a cap cause a change in the AC that gets passed?

[kholt420]

@alphabeets Good question - shows some thought. No, it's not magnetic. It is electrostatic. The charge of electrons on one plate of the capacitor modulates the charge on the other. Besides blocking DC currents as mentioned in the video, the effect is also what makes capacitors form useful filters that only pass certain frequencies of AC current. For electromagnetic effects, look at transformers. (Will that be the "T" when we get there?)

[alphabeets]

@kholt420 Thanks for the response. Could a transformer be thought of as a form of a very low uF capacitor? As in a cap, you have two metal surfaces (in the transformer they are in the form of narrow metal wire windings) that are in proximity of each other but not electronically connected to each other. The thing in between these metal wires (plates) is the wire coating. Is perhaps the difference between cap and transformer simply the shape of the metal surfaces?

[kholt420]

@alphabeets No, they're fundamentally different. Caps work on electrostatic principle. Think of it as the electrons bunch up on one plate. That concentration of charge pushes all the electrons off the other plate but the dielectric keeps them from jumping the gap. Letting them build up (charge) and drain off (discharge) causes the the other plate to fluctuate in sync in useful patterns. Or you can store electrons for use later by delaying the discharge. (cont.)

[kholt420]

@alphabeets so you can get a lot of electrons (current) back out of the cap all at once when you need quick bursts of power but you'll never get more voltage than you had in the first place. That's where transformers come in. Electrons flow through one coil (primary) which generates a mag field. When that field energizes or collapses, it induces a flow of electrons in the second coil (secondary). If there are more or fewer windings of wire on secondary the voltage increases or decreases to match

[kholt420]

@alphabeets (Finally - the cool part) Put a transformer and a cap together. Charge up a bunch of electrons on the cap then discharge them all at once through the primary coil of a transformer with several thousand times more wraps on the secondary and you can get massive pulses of voltage.  This is how a photo flash or spark plug are made to work - caps and transformers working together. Different but complimentary.

[jeriellsworth]

@alphabeets It's the attraction of charges like when you rub a balloon on your head and stick it to the wall. It's not inductively coupled like in a transformer.

[jeriellsworth]

Sorry. Looks like kholt420 beat me too the explanation. :) 

[batterymaker]

That's why I will work on radios, and NOT televisions... :-)

[mebossyounothing]

well done history lessons end technical background explanation , nice

[PeteKillz]

YOUR SUPER SWEEEEEEETTTT!!!! CHIRP!! CHEEP!

[derman077]

I have a modified camera capacitor shocker. fun fun. and why the pig in the jar on the shelf?

[kholt420]

@derman077 Yeah, that was a pretty funny detail. I think it was just to show the "typical" lab of the day. Scientist types were often more generalists than specialists and would poke into anything they were curious about. (admirable trait) Imagine that one making the legs twitch on the pig with discharges from his Leyden jar. (Was that edited out, Jeri?)

[jeriellsworth]

@derman077 No reason.  Just to be silly.

[whisk0r]

Got a nice shock off of a telephone that had been sitting in a cupboard for more than a decade!

[jeriellsworth]

@whisk0r Wow. Wonder what kind of cap was in that thing.

[whisk0r]

@jeriellsworth It was one of those Bell leased rotatory phones. Over built, gnarly goodness.

[ngneer999]

I had one explode a few inches from my face once.  Got the polarity wrong.

[jimbobg65]

Great vid! I love those paper cutouts you make for your videos. I'm kinda curious what 'D' is going to be for the next video! I'm going to guess at Diodes.

P.S. You wouldn't happen to be using noise reduction on the audio portion of the video right at the end 4:45? Just curious :)

[doubleatheman]

Very fun to watch as usual! Thanks!

[Afrotechmods]

The capacitor rocket at the end was awesome

[sonicase]

:|| <- capacitor face

[sciguy14]

Yay Capacitors!

[jwriney]

"Cheep?" Haha, love it.

[horar99]

Warning: several capacitors were harmed during the making of this show.

[rillgen]

so Edison didn't invent animal electrocution, he just invented a way to combine it with propaganda and make profit out of it...

[drberk30]

hey jerie, can you make a video on how to build a small tesla coil

thx

[GentleSavage1]

@drberk30

and it should play SID tunes *g*

There's already videos out there with nintendo 8bit tunes for that,

but I want tesla SID. Now *that* would be "high voltage SID", heh.

[dinomaui]

Love the animation. Reminds me of Graham Chapman's stuff from Monty Python...

"Cheep!"

[reltham]

Excellent, and you put some "exploding" caps at the end of the video too! Nice touch.

[MrTranxistor]

way to go jerie another good video.

[markybhoyuk]

Enjoying your A-Z vids keep up the good work.

[richardah1]

Great video. I'm trying to teach electronics to a friend but this video explains capacitors much better than I can. Thank you.

[FlamingCuntLips]

Any body else getting freay voices in their heads at 4:43 onwards ?

or is it just me LOL

[rillgen]

@FlamingCuntLips I hear something too...

hmmm... it must be Adafruit's subliminal advertising machine in operation... :)

[rjpope42]

T is for Tesla, right??

[horlacsd]

@rjpope42

T for Texas!

[nannerin]

You are adorable!

[MinTrinidad]

......................... :( chup?

[Buchoass]

I watched you with Leo Laporte, he offered you some space in his new place, some 6000 square feet or so? He loves you and I could see why.

Smoking! and the capacitors made some too.

Thanks for sharing your knowledge.

~Cheers~

B.Champagne

[capman911]

We use to do that in school shop class with a capacitor from a vehicle when they had points and a condenser. We would charge them up with a battery charger then throw the condenser at a friend which naturally would catch it and it give them a good little shock. Very good class. I enjoy your presentations.

[FPGAPete]

Haha love how the other bird knows he's next. Great Video. Very informative! Didn't know that was how capacitors came to be.

(the new and improved fezzerpete)

[DPS670950]

I liked the clip at the end where you scorched the oil filled caps.

Having been showered in hot oil and shredded aluminum foil, I see why you didn't want to be around when they went off

I would like to see some intel behind the high voltage SCR's and DC to AC power inverters in one of your videos. I have one that came from Hugh Hefner's 'Black Bunny' jet from the 70's and it works like a champ; delivering 175W continuous / 270W intermittent.

Thanks, darlin'!

[benderman5000]

she is freaken beautifulness inhabitance by knowledge

[SuperDanielB1]

Marry me. ;)

[Pruncible]

"...Cheap?"

[EatCraps]

where were you when i took this class in school! ?

[tankmdg]

man i wish i was married to her

[Cruiser052]

@tankmdg Hey hey hey, get in line. Girls this intelligent are hard to actually find.

[Cruiser052]

@Cruiser052 And no i'm not saying that Women are dumb. -.- It's just hard to find the smart ones.

[ytmachx]

Great illustrations! 

[Films4You]

Ada = Ada Lovelace?

Ada Lovelace, she wrote the world’s first computer programmes for the Analytical Engine, a general-purpose machine that Charles Babbage had invented.

[dnscpan]

nice ^^

[schoolmaster1945]

Great vid...I still like "condensor" and "cycles"....just old school I guess...regards...

[FlyByPC]

Very nice explanation. You have a real talent for explaining things clearly and making them easy to understand. Thanks!

[pieznice29]

Loving these A to Z videos :D
