Only Bob could take one of the most difficult concepts in electronics and explain it so a toddler could understand. Best electronics teacher online bar none.

I'll be danged - I got a level of understanding from this vid that I didn't get from class. Excellent!

Welcome back Bob. We will work with you to achieve the the viewing numbers. I am sharing the videos. Keep it up!

Absolutely brilliant. This is the right way. I get the teachers that start teaching Thevenin Equivalents with "short the voltage sources and open the current sources".<br>That method is algorithmic and helps build a process that will work immediately for students, but it won't help with intuition. This method of "just meaaure the voltage across this element, then measure the current" is way more intuitive. <br>It's like a special case for node analysis, which can work as any general purpose case. It's an incredible tool and a part of practical physics and electrical engineering that brings a ton of concepts together. <br><br>What I love most about Thevenin Equivalent Circuits and Thevenins method of analysis is how it takes the high complexity of Electronics and stands it on it's head by using it's own logic in his favor.<br>Think of it like this:<br>Every element in a circuit, including the conductor, will have parasitic components which cause it to behave as a partial resistor, capacitor, inductor, etc. Imperfections are everywhere so, beyond theory, we can think of any circuit with inherent reactance. <br>So even though transisitors and maybe ICs and other elements have been introduced (and we can still examine and appreciate each individually), it will still all simply down to some complex reactance with a source of power.<br>It is really a marvelous realization and a gigantic contribution to circuit analysis.

Thanks Bob! This really helped me intuitively relate the Thevenin equivalent circuit to the calculations.

I have a much better understanding after watching your videos than I ever learned from college. How and why is so much more important than just learning parrot fashion!

As an electrician, these videos have filled in so many knowledge gaps I had about electricity

Super informative, really good. This is a must see video for people that play the guitar out there. You see a lot of times the question about amp head to speaker cabinet impedance matching. Your video explains it all. In short using speaker cabinets of higher input impedance works fine with amp heads of low output impedance, except you waste power if you do not match impedances. Thevenin s theorem does simplify massively circuit analysis.
