Solving Thévenin Equivalent Circuits: Confused by Different Methods

Click For Summary
In solving Thévenin equivalent circuits, current sources are typically replaced with open circuits and voltage sources with short circuits. However, some instructional videos may present alternative methods, such as treating the voltage source as a load and open-circuiting it, which can lead to confusion. The variety of techniques for determining Vth can overwhelm learners, especially in a subject like circuits that many engineering students find challenging. Understanding the context of each method is crucial for accurate application. Clarity in these concepts is essential for mastering Thévenin's theorem.

Hello,

For thévenin equivalent circuits, I thought current sources are replaced with open circuits and voltage sources are replaced with short circuits.

In this video, the guy replaces both with open circuits, so I am not understanding how that works.


Because of all the different methods I am seeing for solving for Vth, I cannot figure out what to do because I am being bombarded with too many techniques.

The video author is treating the voltage source as the load of the circuit so it is not strictly part of the circuit under consideration. Therefore he treats it like a load and open-circuits it.

I know this stuff is confusing. Small wonder Circuits is usually the least favorite class of Engineering majors!

I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
