What is Norton Theorem? (Norton’s Equivalent Circuit)Norton’s Theorem (also known as the Mayer–Norton theorem) states that it is possible to simplify any linear circuit to an equivalent circuit with a single current source and equivalent parallel resistance connected to a load. The simplified circuit is known as the Norton Equivalent Circuit.More formally, Norton’s theorem can be stated as: “A circuit having any linear bilateral elements and active sources can be replaced by a simple two-termina
