RLC Circuits (10 of 19) Series RC; Calculating Impedance, Current and Voltage

[@PhysicsMomCircusOfScience]

Thank you for making and posting this video. It was so well explained and helped me understand so I could do calculations for my research.

[@stepbystepscience]

Glad it was helpful! You are most welcome.

[@kdeliass]

Your DC/AC playlists are just great! Thanks a lot!

[@stepbystepscience]

Thank you, I spent a lot of time putting them together.

[@Yozollet]

very helpfull, thank you very much, i had this stuff in school about 10 years ago and you helped me repeat and regain my old knowledge, thank you

[@stepbystepscience]

You're very welcome. Glad you are back up to speed!

[@adamderosditte6117]

your videos are the only way Im learning this stuff. Thanks from myself and every body else in class

[@stepbystepscience]

Very nice. Thanks for letting me know.

[@juanrubalcava215]

Great videos, thanks for sharing them with us.

[@yahiaahmed4364]

I think that rule of angle isn't tan^-1 (angle)=Vc/Vr , it is tan^ -1(Vc/Vr)= angle thanks for your tutorial

[@stevelitt]

this is as clear and concise an explanation as one could hope for. i'm looking forward to checking out your other videos.

[@stepbystepscience]

Great, thanks and don't forget to subscribe.

You are the best 👌 👍

[@stepbystepscience]

Thank you so much! Best wishes to you.

[@95jonnyboy]

great video,, i solved them before and we had the same answers,, i guess im starting to understand it.. thanks!!

[@mohammedshaddy9895]

Very well explained.

[@stepbystepscience]

Thanks for the positive comment.

[@drewpierpont3361]

Thanks for your help. I really wish all instructors put instruction first.

[@stepbystepscience]

I thought the all did that, but great comment. Thanks! You can see a complete listing of my videos at www.stepbystepscience.com.

[@Ilyaselho]

I wish that you extend all your precise explanations to mesh analysis, node analysis.... thank you so much

[@stepbystepscience]

Thank you, I will put it on my list

[@samuelbauer7646]

Thanks man, this helped me out!

[@stepbystepscience]

Glad it helped!

[@bansiramsharma3161]

The video was gud ........... Very well explained

[@stepbystepscience]

Thanks!

[@JohnClulow]

Thank you for this clear presentation. I now have a much clearer understanding of the logic behind the calculations. I am still struggling with an issue trying to measure the voltage drop across the resistor using my oscilloscope which is giving a result equal to the source voltage (sine wave) whereas the result for the capacitor drop is what it should be. Probably just something to do with how I'm measuring. Thanks again!! I'll definitely check out more of your videos.

[@kcsamm1069]

Helpful. Thumbs up.

[@stepbystepscience]

Thanks for the positive comment

[@267BISMARK]

i like the dark backgound it makes it much easier to watch. especially at night

[@stepbystepscience]

Thanks for the comment. You can see a listing of all my videos at my website, www.stepbystepscience.com

[@Sk-ew7cn]

Thanks for these amazing videos. Awaiting for RLC Parallel ckt. धन्यवाद

[@stepbystepscience]

You are welcome, I might try to do RLC parallel next. Currently working on electromagnetic induction.

[@milkcreightronny]

Very clear thanks!

[@stepbystepscience]

You are very welcome and thanks for the comment.

[@AceofDlamonds]

Nice. it was helpful.

[@CreativeBangla]

This video is amazing, except one mistake for the "tan^-1". I hope the professor reads this and put a comment on the video so it appears at that time, without deleting this video. Thank you.

[@stepbystepscience]

Thanks for the comment, yes I think I put the notation in the wrong way.

[@pablogimenez8369]

Fantastic!

[@stepbystepscience]

Many thanks!

[@pablogimenez8369]

You sir are a fantastic teacher!

[@tobiasdulla8364]

Very Helpful ... thanks a lot

[@jumasilim7543]

very nice as usual

[@stepbystepscience]

Thanks again for the positive comments.

[@annadkeelenius6217]

thank you ! my hero endeed

[@stepbystepscience]

Nice of you to say. Thanks for the comment.

[@kettelenegaspard685]

wow, those videos are dope bro, i've trying to study them in my book, but it kept gimme headache , than you come

[@stepbystepscience]

glad that you found the videos helpful. And thanks for the comment.

[@AbdulRauf-um4fh]

Nicely explained everything in proper way one Question came into my mind about application of RC series circuit?

[@darrelmahere6339]

Thanks 🙏

[@stepbystepscience]

You’re welcome 😊

[@jhjip-zy7hn]

how do you workout the supply currnet and impedance? giving answers in rectangular and polar form.

[@XGSDEV]

What drawing program do you use for your animations? They are pretty nice, I wonder if you feel the time it takes to produce them is worth it?

[@stepbystepscience]

I am very low budget, McBook Pro, QuickTime and Keynote. That's it!

[@XGSDEV]

keynote -- I will have to check it out :) Anyway, seems like it works pretty well, of course, I wonder how long it takes you to put together the 10 min presentation with it :) I am doing an online EE/embedded course. I got out of teaching, got burnt out writing books, etc. But, one thing I learned was the asset creation could take foreover for a book, and in the end rather than photoshopping a figure, I found I could draw them 10x faster with pencil and graph paper, and then let the art department turn them into drawings. The video stuff is the same, it takes so long to make a "good" presentation with animation, that I feel, just a screen cast and drawing program is much faster -- but I wouldn't mind things looking cleaner than my horrible writing on screen (even with the tablet). Anyway, I have been watching others to see what they are doing and how "engaged" I feel. You talk as fast as I do, that's one thing we both need to work on is slowing down :) Anyway, great beginner videos -- good work. One little typo I saw though and I think its on a number of videos you have tan-1 phi = y/x, what you want is phi = tan-1 y/x, since the original equation is tan phi = y/x, you take the inverse tan of both sides, you are left with phi on the left, and then tan-1 y/x on the right, i.e. tan-1 (tan phi) = tan-1 y/x -> phi = tan-1 y/x. Check it out...

[@stepbystepscience]

Yes it take a while, did earlier vidoes with a tablet but had a hard time writing. Also I can use the Keynote over and over in my teaching. Average video 5 to 10 hours. see al my videos at my website www.stepbystepscience.com

[@jomomma8754]

Thank. You.

[@rendaninefale5426]

Do you convert the rms voltage to peak voltage ? or is either one correct for finding the total current ?

[@prateekpatel851]

Why we use RC in series for making AC to DC convertor without transformer. We can do it by only resistor also?

[@annonynonon]

How come in video 8 of 14, you use V=(I)(Xc) but here 4:22 part b you use V=(I)(Z)? Both problems have capacitors

[@cmistream2899]

thanks man

[@swatimishra7929]

Thankyou sir..

[@kroem6430]

Should the phase angle be negative at the end?

[@stepbystepscience]

Yes

[@WozStoz1009]

What is the v.d across the capacitor in an A C RC circuit.

[@shep7484]

As commented in previous video , it should be tan^-1 181/141 = -.9099 radians and multiplying this by 180/pi = 52 degrees.

[@annadkeelenius6217]

what if I dont know C or Xc ? how can I figure that out ? thanks for the videos

[@annadkeelenius6217]

@Millar i will find out next week after det the exam:-) if I where right or wrong

[@leedaniel3465]

Thanks alot.. I have such a clearer understanding of everything... 2 hr lectures vs 6 mins videos smh.. but I'm confused, from my lectures I've learned that z = R + Xc and/or Xl not z = sqrt( (R^2) + (Xc^2) + (Xl^2) ).. I'm seeing this for the first time..

[@stepbystepscience]

I am not exactly sure what you are referring to but it is a right triangle so you have to take the square root of the sum of the squared values. Simple the pythagorean equation. Does that help?

[@leedaniel3465]

yh i figured after watching the vid again it was all about trigonometry.. I'm just saying that how I was taught to find impedence is Z = R + Xc + Xl, no sqrt, but i figured what you were doing.

[@stepbystepscience]

That is right, the impedence is the sum of all the oppositions to current flow....but you have to add them up the right way...using some trig. Great that you got it!

[@joaogonzalez4082]

Hi, nice tutorial, but the mathematics at the end are wrong: tan^1 (angle) or arc tan (angle) = arc tan (Vc/Vr) that then equals the angle in radians. After getting the radians, to get the angle, you have to transform radians into degress, wich can be done by simply: degree = (radians * 180) / PI . Take care

[@stepbystepscience]

OK, thanks

[@sujalkoirala3675]

How to calculate the impedance without using phasor diagrams?
