Capacitors Are Gaps! How Does That Work?!

That is incredible!
Thank you so much.

What name would the energy have that the capacitor "breathes" in?

❤❤❤❤❤

I'm 42. And this is the first time someone adequately explained to me how capacitors work. Bravo. It's about time.

Science starts becoming interesting when explained by amazing teachers like you!

“Where” is the energy stored inside the capacitor ? 😮

Your videos are lit!!

Short answer: electrons are not moving from one terminal of the battery to another, no matter DC or AC. Its more like they are vibrating back and forth. I idea that one electron, we'll say "Carl the electron" starts at one terminal and travels to the other is complete fiction. And its where the water analogy falls down.

Charge a capacitor that is in parallel to an inductor. Now short the capacitor to itself. All the charges move from one plate to the other in the shortest path (Short). However the inductor creates magnetism. You can use the breath out, to your advantage, because it moves with no wattage. Cold Electricity.

I like your vid here. Probably the most simple complete description up to what we know right now, as to the energy flow of a gap in a circuit or a capacitor.

Have you ever explained the supposed resistance of a superconductor?

Some history. The Leyden jar was the first capacitor, remember? People asked: "Does the bottle size, shape, and thickness matter when storing electric fluids?" The answer didn't make sense if electricity was an invisible fluid, so something else was going on..... FIELDS?!?

I just want to add an orange drop to my guitar. I got Spock telling me about dilithium crystals! Pointy eared #€*£+tax

😱 You just made that up!!! hahaha.

I understand this but I'd never be able to explain it.

unfortunately people still think superconductors have no resistance. Try to find an answers resistance of the superconductors but all I get is answer of zero.

Oh, you have a spice clone now?

The thing is we usually use capacitors in parallel or on a stub leg of a circuit to stabilise ringing, absorb ripple, or to be part of a resonant circuit. These are almost all AC applications or DC from AC at least. Since AC can go through a capacitor (given the right frequency for the capacitance/impedance).
I think it would have been more representative if you had started with the capacitor in parallel to the light bulb load.
And then say the battery gives off lumpy power for some strange (quantum?) reason. The capacitor absorbs the lumps.
This works a lot like an accumulator in a pressurized water system.
If the pressure is high it allows more water into it's reservoir, pressure is low it lets water out to bring pressure back up to nominal.

Right. So, my brain melted when you started writing in Sanskrit.
Edit: What I thought was: If robots become sentient, they better respect us for being able to figure this stuff out and create them. From rock, to this.

What about old capacitors that was never used but it open at the top?

"The transient state of a circuit doesn't usually last very long". As a EE that specialized in circuits that's not true. A capacitor is either used to manage frequencies bands or to filter out transients (which is just a zero hertz low pass filter). Another use is for DC blocking with is an example of a high pass filter. Then there is things like step inverters which gets really fun. The fundamental analysis of L, C, and LC circuits is done using calculus which is the study of "change". "Steady State" is a theoretical condition that is used to simplify analysis but doesn't truly represent reality.

The exception would be something like using capacitors to start a motor.

What are capacitors used for?

Why does an Battery go empty tanks Mr. Crasy

Hi, Many thanks for video, it already gives a lot of information and clarification ,yet i still feel there is something more to it and i`m hoping you will be able to add what is missing at least from my side what i mean is: for me if there is a changing electric field created in the capacitor then this changing E field will create a changing Bfield and this changing B field means an induced emf will occur so i would like please to understand where is this induced emf what is the link between it and the voltage relation in the capacitor I=C dv/dt or V=Q/C, also could you please go further in details may be track an electron path from the battery and the effect of the battery field on it and then what happens at the Capacitor when is the field in the capacitor exactly created can you please show that on the particles the electrons and positive charges where is that field (i mean ok as monopole i can see it out of the positive charge and in the electron charge )but it would be great if you visualise that in a video at the moment it is created in the capacitor , also the electric field is normally causing the acceleration of the charge where does that acceleration start , is there an acceleration from the battery field and then another acceleration from the capacitor new field?, also if those two acceleration are different at the beginning it means the amount of electrons being pushed between the battery and the conductor is different from the amount of electrons being pushed at the capacitor side back to the battery , so if we measure the current at these two different places are we going to get different values? i would really appreciate it if i can get an answer ,many thanks

8'23": with the circuits' switch open and then a battery being put in place, would the "diafragm" move likewise whether the switch was closed (as shown in the analogy)?

Damn man. I've been watching videos about capacitors for days now and can never get a grasp. I beggining to think nobody really understands them fully, like many things in science/tech.

so now explain how inductors store snd release energy

I like to think truth is simple, it just isn't intuitive sometimes. Whenever you understand the true nature of something you realize how that couldn't be in any other way, it is just obvious that it works like that.

Thank you for the analog.

But, but, but... this is just the simplified version! You never explained how those three-electrode flux capacitors work...!

Question: in a charged capacitor, is the charge itself held on the surface of the dielectric (surplus of electrons on one side, deficit on the other)? If so, what happens to an open air-gapped capacitor (such as a variable capacitor used to tune a radio) if a breeze is blowing across it - does the charge get blown away since air itself is the dielectric? If you turn a variable capacitor to full capacitance (plates fully overlapping), charge it then turn it to minimum capacitance/overlap, then back again to full capacitance, will it still have its original charge or will the charge have floated away with air movements while the plates were apart?

Positive particles flowing around? Or negative?

I think electricity is magic and coming up theories and laws about electricity to explain the magic are just the ways that people who can’t do or don’t want to do anything useful are able avoid doing anything useful.

The bound charges in the insulator DO move and stretch the molecular bonds. However, the resulting depolarization is not complete as it would be for a conductor. These moving, bound charges result in a real transient current; but, this current alone is much smaller than the charging current.

I didn't know diddly about capacitors before watching this.

I still don't. 😋

What happens when you remove the voltage source yet the capacitor is still charged with a different potential across its plates?

Way we stuck on electricity, way we cannot produce other kind of electric. From proton or from neutron, named prtoncity or neutrocity.
And electronics devices in new way of current, electronics to protonics or newtronics devices
That is new era started in humanity.

Watch the MIT video on the dissectible capacitor. The plates do not store the charge.

Since the energy is carried by the field surrounding the wire and not carried by the wire, you should make a video explaining what the insulation around the wire does.

One of the best presentations I've ever watched.

I think it's important to note that Poynting vector is a mathematical abstraction. It's not something that you can measure using an instrument. In the end, all electrical circuits can be reduced down to the motions of charged particles (electrons most of the time).

if energy flows in middle of a two plate capacitor and gravity treat energy as mass, then would a strong enough flow create a black hole? (assume its perfectly insulated)

It would be nice if you would indicate current direction correctly, it's time to end that 200 year old fable.
