Thevenin and Norton Equivalent Circuits

In this lab, students will learn about Thevenin and Norton equivalent circuits. Equivalent circuits are simplified versions of complex circuits that yield the same values and can, therefore, be used to make calculations about those circuits easier. For both Thevenin Equivalent Circuits and Norton's Equivalent Circuits, students will confirm the founding theorems of equivalent circuits through a combination of calculation and circuit-building on the NI ELVIS III.

This is lab 4 of 10 in the course, Introduction to Circuits.


After completing this lab, students will be able to:
  1. Discuss the purpose of equivalent circuits and provide examples of use scenarios.
  2. Determine the Thevenin and Norton equivalent circuits for various circuit configurations.
  3. Use equivalent circuits to analyze the effect of changing load resistances.
  4. Identify the differences and similarities between Thevenin and Norton equivalent circuits.
