    1. Chapter 9 Network Theorems

    2. Superposition Theorem The total current through or voltage across a resistor or branch may be determined by summing the effects due to each independent source. Replace a voltage source with a short. Replace a current source with an open. Find the results of using each source independently, and then combine the results.

    3. Superposition Theorem Power is not a linear quantity; it is found by squaring the voltage or current. The superposition theorem does not apply to power. To find power using superposition, first determine the voltage or current, then calculate power.

    4. Thévenin’s Theorem Allows us to make calculations on a complicated circuit where one of the components may have different values. Any linear bilateral network may be reduced to a simplified two-terminal circuit consisting of a single voltage source with a single resistor.
