Norton's Theorem
Electrical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A technique that simplifies a linear electrical network into an equivalent circuit with a single current source in parallel with a single impedance, useful for analyzing load current.
Example in context
“The engineer used Norton's theorem to convert the voltage divider into a current source parallel with a resistor.”
“Mühendis, bir voltaj bölücüyü bir dirence paralel bir akım kaynağına dönüştürmek için Norton teoremini kullandı.”
Where engineers use it
Often paired with Thevenin's theorem, Norton's theorem is used for converting between equivalent source representations, particularly in power electronics and circuit design.
Synonyms: Norton equivalent, Mayer-Norton theorem
Practice: can you use “Norton's Theorem” at work?
A colleague shows you a circuit with multiple resistors and a voltage source and asks how to find the short-circuit current at a specific node.
Show a model answer
“Apply Norton's theorem to replace the network with a current source and parallel impedance.”
