Capacitors in AC Circuits with Phasors | Doc Physics

This continues the previous video's adventure into phasors and how handy they are.

[@neonnebby7370]

"Everybody likes resistors cause they're super simple." YES.

[@TheFootbaldd]

From someone who was a electric plant operator to EE student, I think you are doing an excellent job explaining. In class they tend to want to reinvent the wheel, so I am finding your videos a good review that helps to connect the two.

[@DocSchuster]

And I love how interested and engaged YOU are! Thanks!

[@justabeardedguythatisahero9848]

hi doc great vid

[@Maskva1825]

I graduated from college with degree in electrical engineering very long time ago. I needed to refresh my stagnant knowledge. This is the only video on KZbin that made sense. Thank you!

[@duanebarry2817]

The demonstration with rotating phasor template over the x-y axis is really helpful. It's something textbooks can't really capture.

[@AbhilashThulsidass]

Shoutout from India! You are making me fall in love with physics again through your videos. Really appreciate it. BTW, 'morrow is my finals. LOL.

[@JK-bp9fh]

how did you do 5 years ago and what are you doing now

[@jonjanick6529]

from 15:35 to 15:45 i had an incomplete idea of a capacitor in ac....after 15:45 all the understandings i have about caps came together thank you man, i appericate how you teach and applaud your methods Thank you so much for that visual explanation!!

[@johnsonmid003]

Just learned a month and a half worth of physics in one evening--and to think that I actually went to all my physics lectures. Thanks, you taught me five chapters more than my college professor did. If you get me an A on tomorrow's exam maybe you'll get my next tuition check (but probably not).

[@yourediet]

🤣

[@madinkan]

Brazil here. Your videos are a real help. Thanks Doc.!

[@adaneitor]

One of the best videos i have seen in my entire life

[@thetech685]

I am watching this video 8 yrs after it's release and this is still better than what my profs explain at Uni. Love your excitement and casualness in the video!

[@jeffb.6470]

Your descriptions of the capacitor in a circuit is great. The sound effects you include take it to a level above and beyond any other similar lessons I’ve attend in university or online. You are an incredible teacher! Thank you :)

[@benjtheo414]

Just wow, 2 years of education. Never had such a clear explanation. Thank you very much!

[@dreamlanddon]

this is the kind of intuitive explanation I was looking for. God bless you teacher! I Appreciated!

[@geoptus]

Love the presentation style (and sound effects) - very clear and informative.

[@snatchgrip]

Thank you very much for making such simple and to the point tutorials! :)

[@officialbankz3900]

graphs really simplified that equation, thanks doc

[@joonahulkkonen8346]

Great videos! You really explain the phenomenons understandable way! Thank you!

[@MattyTeare]

BOOM! Now the capacitor is fully charged :) I love how engaging and interesting you make it, thanks

[@AnkitaMisraBubblesAllAround]

Doc, Hello all the way from India. YOU ARE A LIFESAVER.

[@DocSchuster]

Thank you for the blessing! I'm happy you like the videos!

[@yanivgardi9028]

Your videos are brilliant! You make everything sounds so simple...

[@annonymousfox7515]

Nice video man! The explanation on how the current leads the voltage was awesome! Finally get the effect of a capacitor in an AC circuit!

[@reyg8085]

"Okay, we can go up!" Love your videos!

[@ellyvatedaf]

Whenever I'm looking at the current and voltage waveforms in an AC circuit, all I can hear is doc's voice describing the graphs 'OOkay we can go up!' and 'OOKAy we can go down!"

[@Ncik666]

Thank you so much for these videos. I was having a lot of trouble with how my instructors described this, and yet in 15 minutes I feel like I understand it far more than 2 hours of lectures. Saving my bacon for this course!

[@mariamtaha371]

thank you , I started to love physics again , you make it very simple

[@babbalgts]

from India.....DOC...your videos helps me UNDERSTAND these stuffs....in our school....they teach these way too fast....which i cant grab at all..but from your videos....the way you teach...that so fun...loved it..thanks a lot!!

[@christiantoste2295]

sir, you saved my life. I was paralyzed from the neck down. Your video played on my computer and I miraculously got up out of my wheelchair and turned it off. Thank you.

[@joebarker7643]

This really brings things into perspective, thank you!

[@thaplante473]

It is so easy to follow you you make it very clear and easy ! Thank you

[@pierrec9287]

16:19 "ooook we can go up!" I cant help but laugh and learn at the same time! amazing teaching skills!

[@unicore239]

Insane lecture! THE BEST on youtube for this topic

[@hootanbadii1799]

Thanks a lot Dr. Schuster. You are amazing.

[@MrAlbashiri]

Crystal clear. Thank you very much for that amazing explanation

[@Burrahboy]

Another excellent video following up on the RMS video. Thank-you for making this knowledge available in a simple explanation. As Einstein said, if you cant explain it simply, you don't understand it well enough.

[@geraldinebass1389]

Awesome explanation, thank you so much!

[@ThomasTurkington]

You are the best! Simple and interesting!

[@taamardhwaj]

7 years and still this video saving peoples

[@CodyShell]

helpful for circuit analysis! i unfortunately had a horrible teacher that taught solely by powerpoint slides, which doesn't quite work for me. glad i can catch up here

[@000DiegoLabarca000]

This dude´s the greatest.

[@md.shuheburrahman658]

Thank you so much,,,,

[@binxxx1992]

I really like your teaching style. Thanks a lottttttt

[@DocSchuster]

I really like your commenting style! You're greatttttttttttttttttt

[@binxxx1992]

:) hahah

[@yemiobisesan6333]

Could you pretty please do a video on how the various types of transistors are configured as amplifiers. I really don't understand how Class A amplifiers work. A background theory on how various transistors work would be extremely helpful. I'm loving all your videos relating to electronics so far. Your explanation is relatively simple and you manage to pack a lot of incredibly useful information into each video. Yet another 15 minutes of my life well spent. NB: Please I am gagging for your help here.

[@DocSchuster]

Thanks for your kind words. Transistors are high on my to-do list, but I'm stalling because I know it's a very important lesson. It has to be perfect. Unfortunately, I probably won't do it before you need it done. Sorry!

[@kamalesha.p6965]

Greetings from India!.Thanks for making these awesome series of videos :)

[@DocSchuster]

Kamalesh A.P I'm glad they help!

[@BhaktiGyan.111]

Good one....

[@becooool010]

wow wow wow u r amazing, god bless u

[@FU11M00NFARM]

Thanks!

[@vgaulin]

Excellente

[@mack_raymond]

If I saw you, I would give you a high five. Thanks!

[@StephenNu9]

Excellent presentation. If one has an RC circuit, then the continual phase shift continually refreshes the capacitor, enabling it to maintain voltage? I'm wondering if you are going in that direction?

[@dontbother665]

Awesome!!

[@skasti]

Thank you sir

[@Chanderv31]

thanks a lot.

[@user-by5wh4sx1e]

very good explanation,I think that whenever the source voltage decrease the capacitor will discharge current to the source trying to prevent any change in volt, also whenever the source voltage increases the capacitor will absorb current to prevent any change in volt

[@bhaskars6667]

Heyy DOC your videos are awesome!! please post some videos on power electronics!!

[@carlosnoriega7296]

What would the source voltage curve look like in the same graph of the current and voltage of the capacitor?

[@MrWhileloops]

Thank you!!!

[@farahtarek4237]

Umm it's 2021 and WOW! Thank u so much ❤️

[@syedafawara5742]

THANK YOU!!!!

[@mohfa1806]

Hello Doc , congrats on your videos , very professional and you have talent to deliver the information in a simple yet scientific way . I have a question please : when a capacitor is in parallel with an AC voltage source of Vs=4sinwt lets say , then the voltage across the capacitor is also Vc=4sinwt , my question is as follows : as we know the capacitor will charge during the first quarter of the and discharge during the second quarter of the voltage source , and this process will repeat during the negative third and fourth quarter , however i wonder if we say that Vs=Vc then at any instantaneous time the voltage across the capacitor is equal to the voltage across the voltage source , however the capacitor is actually charging and discharging and its actually "following" the voltage source path , so at any instantaneous time the voltage across the capacitor is always a "little" less than the voltage source , so how we can say that Vs=Vc ? ; or isit just an approximation that is acceptable since the voltage difference is always small ? ......thank you very much

[@mikeautostudent5562]

thanks for your video.why they draw polarity for caps in ac circuits? esp for run caps Motors

[@micahmurdoch8314]

i love you!! your amazing!!!!

[@saranvekediler]

You are awesome

[@musicbyvec1955]

This video was lube for the gears in my mind.

[@maramalnahhas8442]

so at Vmax, is the current always zero even if the frequency is high?

[@akshatsharma7339]

DOC I LOVE YOU.
