Solving Thévenin Equivalent Circuits: Confused by Different Methods

[gfd43tg]

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!
