Thevenin's Theorem

Thevenin's Theorem simplifies complex electrical circuits by allowing us to replace a portion of the circuit with a simple equivalent circuit. This equivalent circuit consists of a single voltage source (Thevenin voltage) in series with a resistor (Thevenin resistance). This makes it easier to analyze how the circuit will behave with different loads. Essentially, it reveals the behavior of a circuit from the perspective of a particular component, enabling us to predict how changes in that component will affect the overall circuit performance.
