What is Thevenin's theorem?

Answer by  jpp (84)

Thevenin's theorem is used often in analyzing electronic circuits. This theorem states that linear circuits can be simplified using a single voltage source and series resistance connected to a load.

Answer by  exoticoption (52)

If you consider circuit theory it would be Thévenin's theorem for linear electrical networks states that various mixtures of voltage sources, current sources and resistors with two terminals is equal electric wise to a one voltage source and one series resistor. The theory explains how voltage and resistors can equal his theory.

For linear electrical networks, this states that any combination of voltage sources, current sources, and resistors with two terminals is electrically equivalent to a single source "V" and a single resistor series "R". For single frequency AC systems, the theorem can be applied to general impedances, not just resistors.
