Thevenin and Norton Theorems

This lecture introduces the Thevenin and Norton theorems, which allow for the simplification of complex electrical circuits into equivalent circuits composed of a voltage source and an internal resistance. The instructor explains how these theorems are useful for optimizing heating resistors and when working on complex projects with multiple groups. Through examples, the audience learns how to calculate the equivalent circuit using the open circuit and short circuit methods, ensuring that the current and voltage are the same in both circuits. By applying Kirchhoff's laws and analyzing the behavior of currents in different scenarios, the lecture demonstrates how to determine the ideal voltage source and internal resistance for the equivalent circuit.
