Thevenin's Theorem. "Any two-terminal, linear bilateral DC network can be replaced by an equivalent circuit consisting of a voltage source and a series resistor."This means that a circuit such as the one in Figure 1 can be replaced by a power supply and a series resistor, allowing for a quicker analysis of changes in load resistance,(RO) R3 Figure 1 Some of the advantages offered by this theorem are: • It allows the determination of any given voltage or current in...
