This theorem states that a circuit of voltage sources and resistors can be converted into a Thevanin equivalent, which is a simplification technique used in circuit analysis. the Thevanin equivalent can be used as a good model for a power supply or battery (with the resistor representing the internal impedance and the source representing the electromotive force). the circuit consists of an ideal voltage source in series with an ideal resistor.
