great and beautiful pedagogic approach, need more videos

@rismael9837 3 года назад

MAKE MORE VIDEOS! NO BODY ON RU-vid TAKES YOUR APPROACH TO EXPLAINING> ITS GREAT!

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

@EngineersAcademyLTD 4 года назад

Hi Huba. This video should help to understand this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jV8Okhus4Vw.html

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

Hi Ann - please see previous vid linked here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bV-uxathoVc.html

@frey5218 2 года назад

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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--2aObOh1KX8.html

@socialwar7687 5 месяцев назад

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 5 месяцев назад

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.

@spencerkilby5397 3 года назад

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

@EngineersAcademyLTD 3 года назад

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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--2aObOh1KX8.html

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

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

@nikitadewangan3283 3 года назад

Why j is. Negative for capacitor ?

@EngineersAcademyLTD 3 года назад

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

@winter9619 2 года назад

What if the L the value is ohm

@EngineersAcademyLTD 2 года назад

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

@bahadrguven6268 2 года назад

ıs^2=sqrt(ırl^2+Ic^2) ????????

@EngineersAcademyLTD 2 года назад

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.
