Norton’s Theorem

Norton's Theorem states that any complex electrical circuit with multiple components can be simplified into a single current source (which provides a steady current) and a single resistor (which opposes that current). Essentially, it allows engineers to analyze and understand complicated circuits more easily by replacing them with a simple equivalent circuit. This helps in designing, troubleshooting, and understanding how a circuit behaves without dealing with every individual part. The theorem is especially useful in analyzing power systems and electronic devices efficiently.
