I just want to thank you for how straight forward and easily helpful this was. SO THANKS

[@petercamusojr1545]

For timing circuits I always chose 3 TC (roughly 95%) as the trip point. With all the variants of battery voltages, resistor and capacitor tolerances seemed to give may designs a little more functional design reliability. Then again my efforts was done with graphpaper and pencils. I enjoyed your presentation and graphics. Good job.

This reminds of the time a physics teacher marked my answer on a test as wrong... the question was about the time constant. I took into consideration the 5 TC need to reach almost full charge, the teacher was stubborn that you only needed one TC. In the end he had to admit in front of the class I was right but at the price of him giving me attitude the rest of the semester.

Thank you very much for this video!!! Great stuff. Would love to see a similar video for Inductors with a resistance in series as well!

Reveal all the nuance information that is generally hidden or not explained. Appreciate you guys very much. When I got money to.spare I will be making a handsome donation.

[@selfmade128]

Thanks. Keep simplifying engineering for us!

[@flyball1788]

Good, accessible description - but you might want to edit the last graphic since you appear to still have the battery connected when you discharge the capacitor which is not going to turn out well (except the odd arsonist maybe) :)

Nice explanation of how caps work. Always was curious how they break down and deteriorate in performance from new to aged. When do you pull the plug and replace one? Does it become noticeable if one is being used as a filter in a speaker crossover?. What would be the symptoms in hearing, as opposed to just measuring with a meter? Love all your vids.🤷‍♂️

[@casemodder89]

you replace em, as soon as the led thingy just flashes, the tv doesn't bring up a picture or the elctronic ballast in the CFL light fails to strike the tube or restrikes it out of nowhere serval times.

Seen the new LED explained video? so much detail covered! kzbin.info/www/bejne/hWmwY61ona6Vl8k

[@DrZygote214]

There's something extremely familiar about this. Is this a remake of an old video?

[@EngineeringMindset]

Yes, people keep messaging me asking to cover it so I released it as a standalone video so it's easier to find. Plus hopefully a little extra ad revenue to fund more videos so you get more free content

[@DrZygote214]

@@EngineeringMindset Ah i found it here: kzbin.info/www/bejne/q5SomnifmJKekJY I knew i saw that green chart before. Im shocked that vid was only less than a year ago, thought for sure my memory was reaching way deeper. PS., does charging time for Supercapacitor use the same formula as regular capacitor? Ty for your channel.

[@pavanu629]

Hi, we have a Formula for Capacitor Charging and Discharging Time... Kindly include that in the video Thanks

[@tedundercarriage8183]

which is.....?

thnx 4 this explanation again about caps bro..always curious if what exact amount of capacitors i mean what is exactly formula of capacitance and voltage of a capacitor from the voltage source?

[@kylemasten2552]

Great video!! Think you can do one on UV lights and how they work?

[@enginerepairguy]

Hi paul. At first i loved your ENGINEERING videos. It seems that it has turned into high school physics..

[@EngineeringMindset]

Don't worry, there's plenty more on the way for hvac, refrigeration, engines, motors, cars, valves, electrical etc etc. There's a lot of demand for these shorter electronics basics videos and I try to help as many people as possible to understand subjects they find difficult. Plus the additional views hopefully bring in a little extra ad revenue which I can use to fund new videos and keep providing free content.

[@Oldhogleg]

Why did you leave out the obvious connection with the charge/discharge curve and the natural log e function of (1-e¯ᵗ) for charge and (e¯ᵗ) for discharge?

[@KartikPatel-nt4ff]

[@dido1803]

[@alexbrown1050]

Thank you so much!

[@tvdylan]

surely the charge and discharge curves are different shapesfor different types of capacitor !!

[@nahblue]

Nice video but why not point out how the numbers are related to each other, to make the video more relatable? (the 63% and 100 - 63% etc)

[@ajayjoseph8722]

How will the capacitor charge fully when there is a voltage drop across the resistor? As an example, if it is a 10v supply, with 5V (Vr), how will capacitor reach 10V, when resistor is in series with 5V?

[@PampostReturning]

Thank you 😊❤️

[@darsaishealateja1345]

Can you please explain about power Electronics concepts

[@EngineeringMindset]

We have lots of videos on power electronics, please see our channel videos or website

[@anijikihjygyhoopy5813]

Actually if Resistance we substitute in formula to Voltage/Amperage we could decrease time of charging simply increasing the Voltage.

[@daniloivkovic6634]

Thank you!

[@danic3110]

Is the resistance necessary to charge the capacitor?

[@shadowbanned69]

Beautiful explanation!!! Could you do one for the capacitors they use for car audio. They only list the farad count and nothing else. This is why real audiophiles who want the details never get them. And crappy caps are sold and people get ripped off for buying cheap un needed capacitors who ratings are falsified for a good reason...

[@camthemanis2kool]

Or the capacitor plague caused by capacitor degradation! Maybe a deeper dive into specs like DC bias on different types of caps

[@maharun]

what do you mean by segment?

[@realestateservicessaleshea99]

[@mohamadfazli5575]

How did get 63 % and 86%and the rest? Did you use a formula? Please reply I'm waiting badly

Second 1: 9Vx0.632=5.68V, I don't understand the 0.632V value, where you get this value, how you calculate it or it is measured value???

[@xzoli8]

@@kennmossman8701 ok then that's why I was lost at that point, now I understand, thank you 😁 and I think that formula is a bit complex or complicated somehow because it wasn't show in the video.

[@jugosever]

What if thicker wires were used? They would let more current flow and the capacitor would charge faster, wouldn't it? This calculation would then be incorrect, wouldn't it?

[@psychastria]

Are these constants and formulas the same for all types of capacitors (ceramic, mica, poly, etc.) in addition to electrolytic? Or does each type have its own constants and formulas?

@@andonajohn This sounds cool, how did they react?

[@mmh1922]

[@hquanngd]

It's time to talk about huge "power factor correction" capacitor...

[@Thamli]

I'm still stuck with an issue from a previous video: why does an empty battery give 1,5V and this have to test it with a load to have the correct reading.

[@EngineeringMindset]

The electrons might be built up enough on the plates to give the reading, but it can't sustain a chemical reaction to support a load

[@Thamli]

@@EngineeringMindset wouldn't the multimeter discharge it due to closing the circuit and thus creating a load?

[@marcfruchtman9473]

@@Thamli No, because a multimeter typically has a massively high impedance (or in the case of DC, that would translate to resistance). Meaning that the battery doesn't see any significant load. A multimeter will only show the available voltage. To really test a battery, it's much better to use a load tester. However, if your multimeter shows a low voltage on the battery, then there is no doubt that the battery is weak. A higher than nominal voltage being shown on the multimeter "hints" that the battery is "ok" but it's only a indicator, since it's not a test under load.

Where does the 0.632 comes from?

(e-1)/e

[@nickharrison3748]

current = charge/time. so, current decides charging time.

[@lashlarue59]

In the first circuit why did you have a resistor there at all if the purpose was to charge the capacitor as fast as possible?

[@jayytee8062]

The purpose is to see how to control and measure charge and discharge of the capacitor which is used in various circuits as well as timing circuits.

[@lashlarue59]

@@jayytee8062 So is the resistor there to have a standard moderator for the current flow?

[@jayytee8062]

@@lashlarue59 The resistor is limiting the current flow so it slows the charging of the capacitor. If there was no resistor then it would charge instantly - depending on the capacitors farads value and the supply voltage/current. I'm an beginner in electronics and my explanation is less than precise. Hopefully you get the gist of it.
