Network Theorems - I ENTC 210: Circuit Analysis I Rohit Singhal Lecturer Texas A&M University

The Theorems Superposition Theorem Thevenin’s Theorem Norton’s Theorem

Superposition Theorem When there are multiple sources! The current through, or voltage across, an element in a linear network is equal to the algebraic sum of the currents or voltages produced independently by each source.

Superposition Theorem

Number of Networks Analyzed = Number of independent Sources

Thevenin’s Theorem Any two terminal, linear dc network can be replaced by an equivalent circuit consisting of a voltage source and a series resistor.

Thevenin’s Theorem

Steps  First remove the portion of the network, whose equivalent has to be found  Mark the terminals of the remaining 2 terminal network

Thevenin’s Theorem Steps to calculate R th  Calculate R th by setting all sources to zero, and using reduction techniques. Steps to calculate E th  Return all sources to their original position and find the open terminal potential.
