Parawell! I like it! Amazing series of videos you've done, Dave. Thank you for making them public. I like your use of colors, it's really easy to follow visually
The validity for this analysis is based in theory and involves the introduction of imaginary number j and the complex plane and the understanding that the behavior of the current and voltage that occurs in circuits, operating at steady state, involves the solution to the governing differential equations in the time domain. The solution, in the time domain, takes on the form of voltage drop waveform and current waveform and is of the same frequency and nature as the sinusoidal source applied in the circuit. Having said that, the approach taken in this video is based on representation of the solution waveforms in the complex plane (the vector quantities referred to as phasors) as a workaround to having to solve for the unknown behaviors in the time domain. Even if a person did, they'd find that the only thing that would be unique is the magnitude and phase of the waveforms that solved the differential equations for steady state operation of AC circuit anyway. This version of the work around approach, taken in this video, is instructional in that it graphically reveals the effect and/or result of multiplication and division of complex numbers in the complex plane. In analysis of series circuit V=iZ so voltage drop phasor is a scaled version of impedance. However for analysis of parallel circuit voltage phasor is divided by impedance so current phasors are scaled opposite to the sense that voltage phasors scales in series circuit analysis. The full form for pure inductive reactance is 2πfL*j The full form for pure capacitive reactance is -j/2πfC Where j =√-1
Great Stuff Mr. Gordon. I'm currently a student at my local JATC, If you get a chance I'm sure many of us would love to have you create a video on calculating Combination RLC Circuits. I'm sure I'll be done with AC theory by then but I'm sure it would help future classes!
I have a question: how do I generate a circuit including a branch of LC in series and a branch of LC in parallel such that the result to have dual resonant frequencies at 35KHz and 45KHz?
Great stuff Dave. I am surprised that there are not more viewers. By the way every now and then your refer to the "text book". Can you share the name? Is it IBEW only or for sale to public?
Thanks. Depending on the video, the AC book I reference is "AC Theory third edition - NJATC - Stan Klein", and the Transformer book is "Transformer Principles and Applications - ATP - NJATC - Otto Taylor, Jim Overmyer, and Ron Michaelsis". They are both available used if not new.

Great visual demonstration to make the concepts clear. Videos much appreciated. Hope to see more. Thanks.
Beautiful illustrations of complex concepts. Great vid!
Sir how could one thank you for your support 🙏 ❤ 🙌 💕 😊
Excellent video, thank you so much!
amazing videos Dave!! very well explanation and easy to understand..I would love to share your videos with my students too..
You're awesome Dave!
Dave, thanks from Local 103 Boston

nice work Dave
Wazalamazing! Keep it up Dave!
Wondered if there is a graphical relationship of resistance, and the two reactances in the parallel circuit, the same way there is in series circuit ?
Thank u so much. Amazing class
I have a question: how do I generate a circuit including a branch of LC in series and a branch of LC in parallel such that the result to have dual resonant frequencies at 35KHz and 45KHz?
So, pretty much at resonate frequency XL and XC just give energy to each other in the parallel circuit?
lu 428 thanks dave
Thank You.🖤
Excellent.
just subbed. Will watch
hey man thanks!
Been seeing folks talk good bout you on some electrician pages im on
Thanks for the kind comment.

I watch another channel that has 1.7 million subs and millions of views, but it took like 6 years for the stupid algorithm to work for him.
He joined youtube in Jun 2020
That is the most didactical exposition on the subject I have ever seen on TH-cam.
Excellent video, thank you so much!
