Thévenin's Theorem

Thévenin's Theorem states that any complex electrical circuit with multiple components and sources can be simplified to a single voltage source (called the Thévenin voltage) in series with a single resistor (the Thévenin resistance). This simplification makes analyzing the circuit's behavior at a specific point easier, especially when connecting different loads or devices. Essentially, it replaces complex parts of the circuit with an equivalent model that produces the same electrical effect at a defined connection point, aiding in easier design, troubleshooting, and analysis.
