I am going to have to go back to "electronic basics #1" I am on round 10 and I think I get it but not on the project I am working on.

Just remember 2(pie)FC ;)

brain blown, going back to #1...

Same for me :-)

lol, how about Fourier Transform & Fourier Series and DTFT so on ?

yeah, but i still do not understand what are exactly complex numbers

Vlad Ion, We use Indo-Arabic symbols for representing the values for zero (0), one (1), two (2), etc., just like how we use some random symbols for representing the letters of the alphabet. If the guy who came up with the Indo-Arabic numerals used the symbol "k" for the value of five, we would have written 3 + 2 = k. Similarly, someone started using the symbol "i" for representing the value of the number sqrt(-1). (just like how the symbol for the value of six is "6" or "VI" in Roman numerals). Thus "i" is a number just like any other number. The only difference is that "i" cannot take a physical form. For example, I can give you 1 chocolate, or I can give you -1 chocolate (that means you give me one chocolate). But I cannot give you "i" chocolates, because sqrt(-1) is an abstract concept and probably because of that, people started calling it a "complex" number. Nevertheless, it is a valid mathematical number, and you can build a number line out of it. If you delve deeper into this, you will find that the complex number line is at right angles to the real number line (exp(i*t) = cos(t)+i*sin(t)). This important property of the complex numbers has found applications in real world scenarios like electrical engineering and physics. Complex numbers make the maths much simpler. Hope this explanation helped at least a bit :-).

oh , thank you very much for the explanation. i use complex number every day but i did not know the representation in real life :)

So true

Well, it took me around 6 hours to create just the script. I think professors do not have that much time to prepare their words in front of the class.

Yeah, in college they would break this up between 6 classes and expect you to retain every detail.

Most colleges and universities are politically driven so you need to go to a private college to really learn anything as they don't want you to really know much, just enough so you can pay the grants or fee's. If these professors were that smart why would they work for chump change? The love of teaching as their bills don't get paid? I think not. They would be getting paid big bucks and you wouldn't know they even existed until one of them made a major breakthrough like Zobel, Zener, Schottky, these are real name of people, it's more of a introduction then you have to grow from there by getting your hands dirty and dealing with that magic smoke that appears when you screwed up and maybe get to be friends with some of these people like this guy. When you're first starting out, this video is foreign and everyone forgets and laughs at you as if they were born with all this knowledge. This is one of the main reasons people that go to college never have careers at what they went to college for.

Great Scott Is a great teacher, but maybe you had crappy lecturers? We were taught quite well in uni (not trying to sound douchey, just surprised that your teachers didn't teach you well)

How it is useful in guitar

Akshay Momaya true!

Specially in India lol. I'm studying these topics in 11th standard and my teacher never told the real use of them otherwise I would have paid double attention of mine😔

Thanks for the feedback

Ouch

Or he has hit impedance right in its head. he-he

No problem

nice input

An inductor will support only so much voltage. Once the core saturates the current increases dramatically.

No kidding! I'm just chillin' with a UKposts video and all of a sudden I'm digging around in my brain's back closet for my notes on imaginary numbers.

Have you learnt calculus? Do you know how to solve differential equations? All these comes out when you solve the differential equation for a LRC circuit. You don't have to memorize formulas, infact, i think memorizing formulas is the reason you haven't learnt anything at all.

@@willyou2199 Uncalled for, I can solve differential equations and I never said I "haven't learnt anything at all". I just never knew about that one particular trick

Are you sure? If you solved the diff eq for LRC, you'd get impedance = R+1/(jwC) or R+jwL, depending on inductive or capacitive. Complex numbers have polar representation, ie magnitude and phase. Either you've no idea how impedance is calculated, or don't understand how complex numbers work, this shouldn't be new to you.

@@willyou2199 I never used polar representation for this, I simply never made the connection

Basic high school stuffs

Thanks but we are not there yet

Don't sweat it. Watch it a few times. At some point it will make sense.

I hope you like it

@@greatscottlab Yes it is Informative and help to understand how things works... 😀

Thanks. I give my best.

Thank you

They are my favourite UKposts channels! I'm checking their channels every day waiting for a new video to watch!

Thank you sir you made my day by talking to me(Great Scott)

In my humble opinion its all related to power, Voltage and Current are two components needed to realize work , if you have "all current but no Voltage" ("or vice-versa") you have no power P=V*I This video about by Eugene Khutoryansky about Real vs Reactive Power is Illustrative : ukposts.info/have/v-deo/ap11Z4uZio1oyaM.html

Check out "All About Electronics" channel. I think you will like it.
