Circuit Analysis - Thevenin Equivalent and Resistance - Part 1

In many design instances, we frequently need to connect between circuits requiring an interface. As a result, there are analytical techniques used to handle these situations.

Usually, signals from another circuits feeds into a another part of a circuit, called a load circuit. The one generating the signal is called the source circuit. This interaction between the source and load circuit at the interface is a key design issue.

One of the most valuable analytical tools to help simplifly and deal with circuit interfaces is the Thevenin and Norton equivalent circuits. The video below is one of many videos explaining the Thevenin and Norton Theorem.
