I have been bugged for so long about this until you cleverly demonstrated it here Sir! It's an honor to come across your presentation! I would like to thank you for your time and effort in educating us! Stay healthy so you can still educate us!
You learn the most and the easiest from folks who are passionate about the subject and not from those who does it for living, just a mechanical delivery. Myself, when I know about whatever it is, I get my satisfaction from seeing that the other person got it than my effort to explain. My effort only gives me satisfaction when I see that the other person really got it and also I can not explain to those who clearly do not much interest. In that case I feel nothing. So interest must be there from both side or it is just empty show.
Excellent explanation! I've always been confused when I look at schematics and see capacitors connected in series with an AC source. This really helps to clear things up a little! Thank you for sharing!
Excellent. This is the correct explanation. Capacitor won't allow current otherwise electrons to pass through even in AC. Even most of our electrical engineers get it wrong.
High impedance means it will not put much of a load on the circuit. Low impedance means it will load down the circuit. The lowest impedance would be 0 ohms. So if you had 10 V and a high impedance load a cross it, it may still read 10 V but very low current. However if you had 0 ohms across 10 V, the volts would read 0 V but there would be very high current.
Very good demo. The point that no current actually flows through the cap is very important. The constantly changing charge on either side of the capacitor is important as well. It gives the illusion that current is flowing through the cap which is actually not happening.
@toyu17 Any capacitor can be charged with a DC current, that is what the diode is for. If you use to much current the capacitor can explode. To charge a high capacity capacitor we used a 60 watt light bulb in series with the diode. It will glow bright at first then get dimmer as the capacitor charges. Be careful with polarity, if you charge it in the wrong direction, the capacitor can explode.
Deepest, simplest, and sweetest explanation ever, thank you, but how you explain a coupling capacitor put in series in a circuit, saying it passes AC signal to the other side, thanks again
Thanks Jason Here is another video you may like. Search my channel for more videos. How Capacitors charge and discharge ruclips.net/video/Ag2RujOHqJ8/видео.html
@AllAmericanFiveRadio Yes, AC Induction motor. those black things you see inside a fan with RU, 250VAC 3mF etc written on them are those any different than a regular capacitor? I took apart a window fan and it has 2 of them inside. they wont run without them I don't think. the motors said duracraft on them. I was wondering if you hooked the cord right to the motor if they would work any better. probably not.
Thanks exee11 Think of DC as a battery that never runs down. If it is a 12VDC battery, it stays at 12VDC and does not change with time. So that is why DC only has one potential and one direction. Hope this helps.
This is starting to make more sense. Now I can understand how a capacitor stores a voltage value/charge. Since V = Ed, where E is electric field strength and d is distance, once the electrons are saturated on one side of the conductive plate the comparative "lack" of electrons on the opposing plate help create the electric field ie charge value. Please correct me if this is not true
@78recordrepair The voltage is almost constant from the batteries, but the current stops when the cap is charged. With AC both the current and voltage alternate. If you have lots of voltage and little current you don't have much power, add current and you do.
@toyu17 Charging a capacitor with DC, charges in one direction. Charging a capacitor with AC, charges in one direction and then in the other direction with the AC that is used. When you stop the AC charging the capacitor, the capacitor will be charged with DC at the point where the AC stopped.
@exee11 If it is DC or AC there is no electronics that flow between the plates. The current flow is only due to the charging and discharging of the capacitors plates.
There’s not one answer because it depends on the circuit. They can be used for biasing, signal transfer, oscillators, RF filters, audio tone control, RC time constants, and much more.
Zero potential is not absolute, it is only a reference, much like in the case of gravitational potential. The notion results from mathematical integration between two points. One is conveniently considered to be zero. So ground I guess could be seen as the potential in relation to which all other potentials are evaluated. Also an interesting way to look at ground is that it's able to give or accept an infinite amount of charge without changing its potential.
so if it blocks dc how do smoothing caps and decoupling caps work? if the cap is already charged up how can it smooth anything out if there is no more room?
@AllAmericanFiveRadio not in this fan. its a 3 speed induction motor and the starting cap is just this black rectangular thing with 2 wires going into it. I was thinking of just wiring up the motors to the switch correctly and without the caps. but it's kinda too late as I tossed this fan but I saved the blades maybe I can use them elsewhere.
Good vid. I think the larger the capacity (F) of the capacitor, the longer it will allow to take charge or current; (ie. the longer to charge up to the peak voltage of the input signal).
SIR Watched yr video on CAPACITORS--DC AND AC: 1. LIKED yr video 2. explained well and effective 3. u explain SLOW AND STEADY and hence can be understood clearly by one and all including beginners and students. DONT CHANGE THE PACE AND KEEP IT UP. 4' clear picturisation/video Thanking you vatsa INDIA
A very good explanation and nice simple graphics. Perhaps maybe in the future you could follow up with an explanation of why higher frequencies pass more easily than the lower for a given capacitor.
Thanks for this video. To add to the knowledge: the capacitor in AC will only get enough charge, related to the frequency of the wave. If the interval in which a semi-wave goes isn't enough to fully charge the capacitor, then you'll have it partially charged. Please, correct me if I'm wrong. If this is correct, then having "big" capacitors working in AC has no meaning at all.
Your correct. That knowledge is a little advanced for my intended viewer of this video. Wants the beginner in electronics comprehends the content of this video, advanced knowledge and ideas will be much easier to absorb. Thank you for your comment.
When power is first applied to a non-charged capacitor, the current is very high and the voltage is low, because at first the impedance of the capacitor is very low. But when the capacitors charged the current is very low or zero, and the voltages high because now the impedance of the capacitor is high, because the capacitors charged. So the impedance of the capacitor changes from very low impedance at the start of charging, to very high impedance when the capacitor is charged.
I like your explainations in the comments. Been a residential, commercial, mostly industrial electrician for 15 years and now that ive decided to learn electronics too your videos will be helpful indeed. Thank you very much young fella.
@mamu7mich In this simple circuit there is no lead with the current through the capacitor and the voltage across it on the first half cycle. When the voltage is first applied there is a large current flow and it diminishes as the capacitor charges. Now the cap is charged, and this energy in the cap can ad or deter current flow depending on the AC frequency and the capacitance of the cap. It take time to charge and to discharge a capacitor.
The electrons are acting in the same manner with AC or DC. With DC, it does not change direction, so as the plates of the capacitor continue to increase with a charge, the charging rate decreases as the impedance increases. When the capacitor is fully charged with DC, it's impedance approaches infinity.
Before the discovery of the rectifier the theory (best guess) was that a current (electrons) flowed from positive to negative. When the rectifier was discovered they found that electrons would not flow from the positive cathode to the negative plate of a vacuum tube. But if they reversed it, Negative on the cathode and Positive on the plate Current (Electrons) flows. So electrons flow from neg to pos. Some people never reversed the current arrow, why, I don't know.
CameramanLink At the plate of the detector it may have 90VDC, if the audio cap did not block DC you would have 90VDC on the grid of the next audio amp tube instead of just a volt or so. neat stuff isn't it
Great demo, Now a question, I am trying to figure out how to make a Start /Run AC Paper in Oil Capacitor for Air Conditioning and make into a Filter Capacitor, is there anyway to make it polarized? I know that AC Start / Run has Positive and Common, how do i turn that to positive and negative? I need to be able to use the negative and solder it to the AMp chassis....Pls let me know? Just trying to get old school, have several RCA 2a3 and Hammond Organ amp that came with 6 to 10 MFD oil Capacitors that are polarized. thanx a million....
If you have a non-polarized capacitor then it does not matter how you install it in a circuit, as long as you do not exceed the work voltage of the capacitor. If you have polarized, electrolytic capacitors, they must be installed correctly, (positive to positive, negative to negative), or they may explode.
@coondogtheman1234 besides a starter capacitor there is a winding also to start the motor and a centrifugal switch that opens at about 75% of full speed. That circuit shift the phase to start the motor rotating. Google "start capacitor" or "AC motor" there is lots of good information.
Hei: Mr, Your explanation of Capacitors Block DC & Allow AC flow is very Brief. Basically AC electron flow simply travel forwards & backwards cycle in between Capacitor Dielectric inside. You did now explain Why & how first order Crossover Speaker Capacitor can filter & allow AC electron current to flow/pass through Dielectric insulator. Please provide RUclips video proof & explain in deatail files if you knows. How it works? Tks...
CameramanLink At the detector plate of an AA5 you will have RF and Audio. You do not want to amply the RF so the RF is drained off through a pf cap to ground. The RF energy is transfered though this capacitor to ground. The audio continues though another capacitor to the grid of the next audio amplifier. The audio cap and the pf cap both block DC.

Wonderful video, you're an excellent teacher. The question which I can't seem to find an answer to relates to coupling capacitors, which pass AC while blocking DC. It's a beginner's question! In a DC circuit, isn't there *only* DC? I don't understand a low pass filter which shorts the higher AC frequency noise to ground while the lower frequency DC signal (blocked by the capacitor) can continue down the circuit. I don't understand how AC and DC can both be in the same circuit? It sounds like the dumbest question but I keep seeing references to AC being allowed through while DC is blocked in the same circuit. I thought a DC circuit was DC only (flat line on the oscillator), and AC was AC (sinusoidal) only, and they never occupied the same space. Thank you!
