AC Circuits - Impedance & Resonant Frequency

This physics video tutorial explains the basics of AC circuits. It shows you how to calculate the capacitive reactance, inductive reactance, impedance of an RLC circuit and how to determine the resonant frequency as well as the phase angle and the power dissipated in the circuit. This physics video has plenty of examples and practice problems for you to work on.

Physics 2 Final Exam Review:

[trunkmonkey]

"In this video" ...chills...every time. Man is the GOAT

[DVIBEZ]

if teachers in schools and professors in colleges were like this guy, we would have seen flying cars and buses since 1990

[Oly]

I'm studying to become a industrial automation technician, and your videos have been helping me a lot, thank you very much.

[multione]

you could literally get a degree with what this guy teaches its insane. Forget going to class you get everything you need from this guy !!

[kelloginc]

Thank for this! I'm in college circuit class and we're going over this now! Love your content <3

[therealestofall]

I'm doing my third year in varsity majouring in Physics and Chemistry....And i would honestly say, without this Man's help, i wouldn't be here💯

[basmala]

I am from Egypt and I want to tell you that I am very happy to know you, I really understand from you more than my own teachers you are so professional in teaching💯💕

[franzdelrosario]

I'm so happy you upload a video again after month, I would like to say thank you very much you really help me everyday when I'm struggling on my quiz

[jpdpnjn]

I watch your videos for fun at this point bc I don't even have to know this. Thank you for videos seriously, you have helped me so much in physics.

[xmanlatter]

Your channel is what makes YouTube/social media an asset👍🏾. Knowledge is king keep up the good work!

[DC_Excel]

First time commenting here, I just wanted to say a big thank you for all your good work.


I've been learning from your videos for years now. Especially when my exams are very close. You are always my lasy hope and have never disappointed me
Thanks, man.

Anytime I see your channel under a search result, I know that I'm going to understand it.

[tdhanasekaran]

This is a fantastic video on AC circuit analysis. Very clear step by step explanation with beautiful Q&A type worked out examples. I got a clear explanation of resonance in RLC circuits The video makers voice over is clear with the correct pacing and easy to follow. Big thumps up!.

[saytans]

wooooww, im on first semester taking chemical engineering, and it have electrical stuff.

and this guy just drop this, amazing, pure amazement.

[vidaserenelarracas]

Thank you so much so informative! I was having a really hard time with this for my finals! Keep up the good work! Thanks again!

[Sportie-x]

The teaching method of my teacher is difficult for me to grasp, but your approach is much simpler. I appreciate your tutorial immensely. Thank you!

[kevinwehleit]

Wow! I wish this came out three weeks ago as I had my AC exam last week. It's ok, I passed. I really appreciate all your content.

[thecalmboyy]

so, I study physics, I have a lots of problems with math and physics cus your teachers don't explain a lot... BUT YOU, YOU SAVED MY LIFE BRO!!!

[Flourishdedua-nkjd]

This is my first time commenting here😊..and i can really say i commend this tutor because i am to learn this tomorrow and i now understand it before the class.
Thank you sir.

Near the end of the video:

Power Dissipated = (I ᵣₘₛ)² × R, emphasis on "rms".
Power Dissipated = (I ᵣₘₛ) (V ᵣₘₛ) cos θ.

Hence, both formulae give us a value of 5.95 Watts instead.

Other than that, awesome vid, my mans 👌🙏🙂

[sarahantony]

THANK YOU SO MUCH!!!! 😌❤️
I CAN FINALLY GET THROUGH ENGINEERING BECAUSE OF YOU 😭
