Is it possible for the capacitor charge be different in point one for example?

[@l0I0I0I0]

Just wanted to say I really love your material! Thank you for posting it!

[@nihil9456]

This KZbin channel is the sole reason why I feel like I'm capable of pursuing higher education and a career in electrical engineering. Thank you!

[@kevincampbell8298]

Lots of math involved! Spent 3 yrs studying electricity and electronics. Go for it!! Take some courses.

[@RussellCambell]

Maybe just keep learning here. Buy a lab setup and go crazy :)

[@THEMFORMATION]

Trust me, you don't need a higher education. The info is already out here on the web, you just have to put the pieces together

[@SHREDTILLDEAD]

@@kevincampbell8298 we need more channels and videos with the math. I am learning to work on my tube amps , and trying to take the guess work out. Recently replaced my filter caps on a vintage amp but I would like to know the exact esr worst case ratings for capacitors that are not listed on my table, so basically for now I guess I should just calculate the difference in capacitance ratings using the values above and below on the table. Some say it should be based on manufacturer info but good luck finding that for every capacitor you ever have. This is the kind of thing I think is important , because in these days there is no telling how long someone has caps on the shelf, because isn't it best for them to have currents applied every now and again?

@@THEMFORMATION You don’t take take the course because the information isn’t out there. You do it to have access to all the learning resources, equipment and to get verified engineering degree. Companies don’t tend to trust self study engineers as much unless they have some diploma to back it up

[@ClassyJohn]

im self taught in electronics and i want to say “thank you” for making these videos.

[@jeanpaulkyokya2341]

It's the understanding of "smaller" concepts such as "How time constants affect charging and discharging cycles of capacitors" that end up making anyone interested in Electronics be better. Thanks for helping in making the job easier.

[@fadysafwat4545]

I've studied a full semester to learn what you just said in short video and didn't understand it as I've understood it now from your video ... Just one of the greatest channels on the KZbin which really explains and clarifies electricity Keep the greatness ❤️❤️

[@skyborne1772]

Your channel is better than the schools that teaches. Keep it up. I learn more here even after graduating. Thanks!

[@TheHellYeahMan]

This is exactly what I’ve been looking for, you’ve read my mind! Thank you 👍

[@OK-bv9tf]

You deserve at least 10M subs. As long as your videos are available to watch on youtube unless youtube suddenly crash, it will always be very valuable for the students and linke-minded people for the future to come.

[@michaelmejia8678]

This video was presented so beautifully, I nearly cried. Why couldn’t my college professors have explained such subjects so simply?

[@tmelectricaltutorials2851]

Your videos is really great and with clear explanations, you are better than when i study on school before. I like your channel.

[@johnkesich8696]

Would you please comment on this excerpt from NIST's WTC 7 FAQ? "Stage 2 (1.75 to 4.0 seconds): gravitational acceleration (free fall) ... During Stage 2, the north face descended essentially in free fall, indicating negligible support from the structure below. This is consistent with the structural analysis model, which showed the exterior columns buckling and losing their capacity to support the loads from the structure above."

In my school we haven’t yet learned about capacitors or even electrons but I know all of it

[@tahahazim2209]

I had learned in this week the circuit RC(resistance capacitor) in the school 🙃🙃

[@floky1800]

Your videos have really helped me with my apprenticeship Thank-you 👍

[@Yash-Gaikwad]

Best explanation ❤

[@totallyfrozen]

This is the video I was waiting for. Thanks 👍🏻

[@joshy0369]

Good stuff 👏 👍

[@Jojo_clowning]

I appreciate the simplity in these totally will get a good mark in my test

[@bitebonumbere1426]

Another nice video. Thanks for the manual subtitle upload.

[@JLCPCB]

Amaizing video! 🤩

[@AtAGlimpse_UB]

can you make a video explanation all the complex math of these caps and inductors? the math REALLY STRESSES ME OUT!

[@EngineeringMindset]

We've made a more detailed capacitor calculation video previously, with worked examples, check it out

[@richardwhalen1859]

Thanks great presentation

[@nicholaswilliams5915]

Can you do a video on delta and Y connections in power systems?

[@EngineeringMindset]

Have you watched our star delta and 3 phase videos?

[@nicholaswilliams5915]

@@EngineeringMindset no I havn't. I'll take a look right away and thanks for all the videos. They have greatly helped me as a student.

[@ilya9399]

Thank for lesson! I know that these resistance-capacitors circuit can be used in the time relay.

[@EngineeringMindset]

Sure can, check out our time delay relay videos

[@muzdokgober9371]

Thank you for the video

[@MJ-gq9nv]

Almost understand this hear learning about caps for rc electrical science wanting to make my own cap pack to offset sag and I believe if I study the math I'll get it thanks

[@dakshagarwal5416]

Hey please make a video on zener diodes and all other different types.

[@charlescox290]

Do these formulas also apply to Leyden jars?

[@thesilentonevictor]

Great video

[@user-qg3ss9nt4e]

Pls. Make a video about how switching mode power supply works.

[@user-ch9di6by3b]

Can you please make a video on hydraulics such as in earth moving equipment. Thank you!

[@sudheerkumar5966]

Very good sir

[@magicbox9371]

So is the resistor necessary to charge?

[@PampostReturning]

Thank you.

[@okithdesilva129]

Hi, please can you do a topic on air Compressors (screw, scroll, piston, turbine etc)?

[@EngineeringMindset]

Please watch our video on compressors

[@ApexPredatorWithSungGlasses]

Why an exponential curve tho for both charge and discharge? 🤔

[@farmerjohn6192]

because i = C dv/dt while the resistor gives a linear relationship between its voltage and current. The solution to such differential equations is the exponential function being the integral of 1/x

[@SheikhN-bible-syndrome]

I'm confused so if I have 6 3000f 2.7v caps wired up for a 14.4v 500f load capacity and then discharge it at 1ohm how long will it take?

[@farmerjohn6192]

So that’s 3000/6 = 500F with a voltage rating of 16.2V. The time constant is RC = 1 x 500 = 500s. So after one time constant the voltage will be 9.1V. To discharge will be 5 time constants per the example

[@SheikhN-bible-syndrome]

@@farmerjohn6192 so 500amps of power for 1sec and it will have dropped to 9iah volts?

[@oxygenirani2876]

Perfect

[@adithyafpv]

It can also be charged directly without a resistor right. Why do we need a resistor in between

[@zenniz1992]

You can do but the current flowing through the cable will be very high. It won't be dangerous for a 9V battery as the max ampere can only reach about 1A. If you use for example 12V lead acid battery, the current can go dangerously high which will burn the a small gauge cable. The resistor is to limit the flow of current.

[@VidarrKerr]

So, when little Billy disobeys his dad and takes apart his PC PSU and his finger touches one of the big capacitor leads, it is really only the first two "Time Constants" we are interested in, because after the second, he is basically dead.

OK so I feel charge capacitor with electric light?

I am sorry, but capacitors are not ezponential but logaritmic...
