Agenda0:12
A Word on Linear Circuits Textbooks....0:19
Review4:07
Review linear circuits by covering ohm's law, power, and sources, plus series and parallel resistor rules, nodal analysis, superposition, and Thevenin and Norton equivalents to simplify loads.
Finding a Thevenin Equivalent Circuit with Multiple Source Transformations4:06
Apply a three-step process of repeated source transformations to convert a voltage source in series with a resistor into a current source in parallel, yielding the Thevenin equivalent.
A Three-Step Process to Find the Thevenin Equivalent of a Circuit5:34
Discover a three-step process to find the Thevenin equivalent for circuits without dependent sources. Remove the load, compute open-circuit voltage, zero independent sources, and determine resistance looking into the circuit.
Example of Using the Process to Find the Thevenin Equivalent of Another Circuit3:55
Demonstrates finding the Thevenin equivalent by removing the load, computing open-circuit voltage (1.15 V), and calculating the Thevenin resistance (2.13 Ω) via parallel simplifications and source transformations.
Thevenin Equivalent and the Norton Equivalent2:09
Explore how to convert a voltage source in series with a resistor into a current source in parallel with a resistor, forming Thevenin and Norton equivalents.
Another Complete Example of Finding the Thevenin Equivalent Circuit14:10
apply a three-step method to find the Thevenin equivalent: disconnect the load, compute the open-circuit voltage, then zero independent sources to find the equivalent resistance.
Summary0:50
Apply a simple three-step process to find the Thevenin and Norton equivalents, then use a source transformation to switch between representations for modeling complex circuits and loads.

Description

Day 19 of Linear Circuits. Thevenin equivalents builds upon our previous topic of source transformation. It is an even more powerful tool to analyze linear circuits. Using nothing more than Ohm's Law, we show you how you can transform a linear circuit into an equivalent circuit that often is much, much easier to solve.

The material covers all of the lecture material from an nineteenth lecture in a traditional, sophomore-level linear circuits class.
