Thevenin's Theorem
Electrical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A method for simplifying a linear electrical network into an equivalent circuit consisting of a single voltage source in series with a single impedance, used to analyze the voltage and current at a specific load.
Example in context
“We applied Thevenin's theorem to derive the equivalent impedance seen from the load terminals.”
“Yük terminallerinden görülen eşdeğer empedansı bulmak için Thevenin teoremini uyguladık.”
Where engineers use it
This theorem appears in linear circuit analysis when calculating voltage across or current through a specific load. Engineers use it to simplify complex networks without solving full equations.
Synonyms: Thevenin equivalent, Helmholtz-Thevenin theorem
Practice: can you use “Thevenin's Theorem” at work?
A technician asks you to explain how to reduce a bridge circuit with multiple sources to a single source and resistor for load analysis.
Show a model answer
