A.C. Circuits : Phasors, Impedance, Fourier Transform, and how Inductors and Capacitors work

For years I’ve tried to demonstrate to my peers how a photon “travels” through multiple axis and my friends couldn’t grasp my vision (maybe my explanation was rubbish) now I can show them!

[@kingsleyakpeji5447]

Very great work with the graphical illustrations. You really demystified areas of AC signal and circuit response that have been vague to me for years. Please, keep up the good. I am looking forward to more of your videos.

[@blitzkringe]

[@jaybrown6174]

What great video’s! I wish they had been around in the 70’s when I was in school studying electrical engineering it would have made things much easier to comprehend.

This is an excellent series of videos, I am really glad your channel is starting to get the attention that it deserves.

Please, mention the softwear you are using to do the simulation. I will really appreciate your effort.

[@mmenjic]

2:08 imagine the wave that would trace the square on the lower right graph (instead of circle), now imagine that trace in 3D in upper right graph, now look at it from the side to get the graphs on the left, that wave represented on either of the left graphs upper or lower should trace the line like it is going up and down at certain speed and then pausing at the top and the bottom of the amplitude in order to make the square traced on the lower right graph. Given your wave is tracing circle similar should apply, wave should speed up in the middle of the amplitude and slow down at the top and bottom portion of the graphs on the left because if we take the example of the lower left graph compared to the lower right graph we have wave tracing the line up and down in the left graph but looking at the right circular graph wave is tracing the circle so in the middle portion of the wave majority of the motion is done in the imaginary axis but at the top and bottom portion of the circle majority of the motion is made in the real axis which we do not see in the graph on the lower left so it should be represented as slowing down of the motion in imaginary axis which is what is represented in the circular graph. Why is this not represented here and on the bunch of other places if this representation is correct than try to sync the speed of the circular (ones on the right) and sinusoidal (ones on the left) graphs? I am not that smart to say what does this mean, I am just observing that there is something wrong with this representation and that these left and right graphs cannot be synchronized to trace the wave at the same and constant speed so that the point which is tracing this wave always shows the same value of the imaginary and real axis a in same time on all 4 graphs, so please explain it to me if I am the only one seeing this, and if I am not the only one why no one of you did not ask this before? I dont know did I explain well what is I am asking, but I hope I did and someone would understand, one more way to ask is if we look at the bottom right circular graph and observe the point which is tracing the circle, look at it in bottom portion of the circle - when it is close to imaginary axis - when that point moves one unit left and right from this axis it is moving mostly plus or minus measured on real axis and stays pretty close to minimum of the imaginary axis. But in the same time looking at the graph at the lower left, point tracing the wave moves at the constant speed, so it seems like it is moving more on the imaginary axis than it should compared to the circle at the right. And these two graphs should agree with each other because they are representing the same thing. If we say that the point on the circular graph at the right is at the time 0 positioned at the 0 on the real axis, and at the position -4 on the imaginary axis, then that point at the time +1 is positioned at the -1 on the real axis and -3.9 at the imaginary axis, but at that same time +1 looking at the sinusoidal graph on the lower left this point is not there, it is already at the -3 position on the imaginary axis ?

They move triple S because of three D. Numbers swing. Resistance of numbers is increase or decrease. Projection on planes is what we call curves. Though they never move. A wrap around of negative infinity to positive infinity. Because they project they have other values.

Does the 90° phase shift created by the capacitor imply that the capacitor is always "charged enough" to have an equal voltage to that of the source?

[@369ranch]

Thank you for this video!

[@01k]

Great work

[@Camptonweat]

Nice work - It's worth mentioning though that the complex representation should come with a complex conjugate so that I, V etc. remains real-valued. Leaving the conjugate term implicit is fine for linear circuits, but can create confusion when it comes to nonlinear interactions e.g. mixing or power dissipation if the conjugate term is inadvertently omitted.

[@TheSiGuyEN]

I think I talked about that in my laplace transform video

[@stargazer7644]

I wish I understood what this means.

[@Camptonweat]

@@stargazer7644 Well I can try to explain it in simpler terms - basically it means we need to pair up our complex exponents in the form exp(i*x) + exp(-i*x) - this retains the algebraic simplicity of using complex exponents, while keeping the function real-valued. If we then try to compute e.g. the power through a resistor using V^2/R, we get both the DC and 2nd harmonic terms as we should. Without our conjugate pair however, we don't get the correct result.

[@keylanoslokj1806]

[@paolocaruso2121]

Very interesting video and very clear. I have only a question. I think 1 MHz, which is the source frequency in the RC example, does not match the 90 phase shift frequency in the Bode diagram. In fact, the right frequency is not 1/RC,which is the pulasation, but 1/(2*pi*RC) which Is the right frequency when the two waves are 90 degrees out of phase. Tell me if I'm wrong😅. For the rest, very interesting video and very clear at all👏🏻👏🏻👏🏻

[@TheSiGuyEN]

can you specify the exact point in the video you are talking about?

[@rossellacurcio8101]

@@TheSiGuyEN from 12.24 the example of alternating signal in RC circuit

[@TheSiGuyEN]

I didn't say that the source and the cap voltages are 90 degrees out of phase. I said that the voltage across the capacitor lags the current flowing in the circuit by 90 degrees. and that what happens at any frequency there's nothing special about 1MHz, the capacitor forces the current to lead the voltage across it by 90 degrees. and yes you are right, 1MHz isn't the 3dB frequency. But the 3dB frequency (1/(2pi*rc)) is the frequency at which the input voltage and the output voltage (the voltage across the cap) are 45 degrees out of phase not 90. thank you :) if you have any questions or suggestions please let me know here or in our Reddit community.

The "War of the Currents" was between Thomas Edison and George Westinghouse. Tesla had no part in it; in fact, Tesla admired Edison and spoke highly of him.

[@BharatkaEkBeta]

What are you even talking about dude?? Tesla used to work for Edison and due to Edison not paying him and not giving him credit for some of the patents that he helped Edison with he left his company and then later joined George Westinghouse. The Westinghouse polyphase AC system is based directly on the AC induction motor which Tesla was awarded a patent for. To say he admired Edison is a stretch to say the least.

They are now trying to mock Tesla too..

[@odissey2]

The Edison is known for stealing patents from other inventors, and was sued several times for that. He likely contributed to the murder and disappearance of the witnesses in those trials. It is safe to say, that he was a shrewd businessman, and likely hadn't invented anything substantial by himself at all. Perfect american.
