Using Phasor Diagrams to Evaluate Series and True Parallel RLC AC Circuits

engineers.acad...
This video outlines how phasors (phasor diagrams) can be used to evaluate resistor-inductor-capacitor (RLC) circuits in order to determine the currents through different sections of the circuit.

MAKE MORE VIDEOS! NO BODY ON KZbin TAKES YOUR APPROACH TO EXPLAINING> ITS GREAT!

[@1973jdmc]

You are now officially a SUPERHERO- MR FANTASTIC - THANK YOU sooooooooo MUCH

[@tchakountehyacinthe6340]

great and beautiful pedagogic approach, need more videos

[@alandkamaran3696]

youre the best, love ur accent

[@ritesha8050]

awesome, just the video i needed. thanks a lot

[@pizzamechman8380]

It finally makes sense.

[@HawkDnB]

which previous video should i watch to understand how did u calculate the angles with the j stuff?

[@EngineersAcademyLTD]

Hi Huba. This video should help to understand this: kzbin.info/www/bejne/oIebgJ6eqthnjNk

[@Festus2022]

Very nice video--> Thanks a lot!

[@frey5218]

I still cant make much sense of the complex number from the link you gave in another persons comment that can be applied here :') But I do understand most except phase angles. Thank you :) Our teacher legit just gave a powerpoint of notes but half if not most of them are exercises and filled with formulas that arent explained well. Its hard.

This video might help in converting from cartesian form to polar form: kzbin.info/www/bejne/Y2PEgJWFnZZ-jpo

takes me back to College Theory 1983

[@EngineersAcademyLTD]

Nothing much has changed!

[@antor54]

This method of evaluation is good

[@moheuddinsakib7416]

Thank you so much

[@eggxecution]

vid is good but speak a little louder next time. i need to max my volume to hear your voice

[@socialwar7687]

you explanation are easy to understand. just one question, at the IRL part where V/ZRL. why did Z become 100V at an angle of 0 instead of 100V at an angle of 50? or is it that the 50 is a frequency and it does not affect our angle? thank you.

[@EngineersAcademyLTD]

What you say at the end is right - the frequency is 50 Hz which is a different thing to the angle. Hope this helps thanks

@@EngineersAcademyLTD i see, now i understand, thank you so much.

Thank !

amazing!

You are best 💃💃

[@spencerkilby5397]

The formula for Z is sqrt(R^2+Xl^2...) is it not? you did not apply the squares. how come?

[@EngineersAcademyLTD]

Yes this is the formula for the magnitude of Z, and we also see the same when converting from rectangular to polar form. For example when 10 + j10.37 becomes 14.41 at 11:43 in the video. See this vid for more info on converting from rectangular to polar form: kzbin.info/www/bejne/Y2PEgJWFnZZ-jpo

[@paulosouza449]

Thats the formula for the phasor Ie polar form for the given imaginary number

[@nkkalitastudy9542]

Thank you sir

[@annnguyen9595]

can you please add the link of previous videos about the conversion? thanks

[@EngineersAcademyLTD]

Hi Ann - please see previous vid linked here: kzbin.info/www/bejne/mIeQpquXqc2ijMU

[@professor902]

great

[@winter9619]

What if the L the value is ohm

[@EngineersAcademyLTD]

It just means that you already know the value of XL and you don't need to work it out at the beginning.

[@winter9619]

@@EngineersAcademyLTD oh thanks man.. I Ady figured it out yesterday 👍

[@nikitadewangan3283]

Why j is. Negative for capacitor ?

[@EngineersAcademyLTD]

Reactive components - inductors and capacitors - both cause phase shifts between voltage and current. But whereas current lags voltage in an inductor, current leads voltage in a capacitor, and so one is expressed as +j, and the other as -j

[@bahadrguven6268]

ıs^2=sqrt(ırl^2+Ic^2) ????????

[@EngineersAcademyLTD]

No - because these two currents don't form a right angled triangle - this pythagorean approach could only be applicable where the vectors are separated by 90 degrees.

[@bahadrguven6268]

thx

[@yusprogres5271]

Yes
