Thevenin Equivalent Circuits | Basic Circuits | Electronics Tutorials

Thevenin - the name, for some reason, seems to strike fear into the hearts of Circuits 1 students. In this tutorial, we'll go over the steps to create Thevenin Equivalent Circuits and learn why it can be so helpful. Working through the steps of how to create a Thevenin equivalent circuit will be followed by two examples showing how to apply those steps in a practical way.

Your tutorials are great.
20 years ago, the resources online were not so good and many filled with people not so kind! lol
Before I had done any college for E.E., just finding someone online in those days to provide the explanation and simple circuit to produce a virtual bipolar supply from a single ended only took me about 2 *YEARS* before someone was decent enough to help me without demanding I build a *shrine to them lol.*

Very well-made content. I think your channel fills a spot on youtube, most of the other equivalent channel's contents are showcasing (not teaching). The only major thing that sets you back is the upload frequency.

[cavelinguam]

Love these videos. Perfect for practice.

At 11:55 you say the resistance is in parallel, but at 12:40 you calculate resistance in series. Could you explain why it changes from my understanding you're pulling the same values from the same circuit but combining them differently ?

[lourdesleung]

This guy is like Paul Rudd if he pursued engineering instead of acting

[brucemurdock]

Why do we replace voltage sources with shorts and current sources with opens?

[cdo]

During the second step of removing the load resistor in the second example, what is the issue with simply removing the 50-ohm resistor and keeping the voltage sources in the exact same spots? Obviously it's wrong and you'd get 10-ohm and 20-ohm resistors in series rather than in parallel--but what's the concept error that I am missing here?

[chrish]

As someone new to the study of electronics, can you clarify what you mean by "load"? Can you give me an example of a load?

[jninothemc]

Hi. For the second example. How did you get 6.66 for thevenin equivalent ?

[SOMYAGUPTA-jzqr]

Tonns of thanks to you sir. It was a reallly helpful video.<3<3

[DaEpicKiller]

At 2:57 you mentioned that the 3 resistors will be in parallel, but how? If you place a short at the two voltage sources, wouldn't the first resistor get shorted out since it is in parallel with R=0? Then the Req as seen by the load should be the two other resistors in series with each other.

[kamilshwaita]

In example 2, when you were finding Req you did 20+10 but aren't the resistors in parallel ? wouldn't it be 200/30 ?

[RedXlusive]

Is there another video of yours I can watch to better understand this because I am having a hard time following

[fisforfriendship]

why did u not draw out the current source in the sample

[MSDTTC]

Vth can not be 5V based on one source other source also contribute ...

[edudaverdc]

At 7:00 why does the short circuit cut out the 200 Ohms

[shermangeorgiadis]

Sourcing and sinking. Tutor us on these concepts, please.

[halitozgur]

Please figure out how to animate the stuff you draw on paper. Believe me, you will get more views. I mean the background is perfect. You just need to make other things like your thumbnail and animation fancier.
