5.5 THEVENIN'S THEOREM AND NORTON'S THEOREM

The problem of solving a circuit with different load networks connected to the same delivery network arises in Electrical and Electronics Engineering quite often. We do not want to write the same node equations or mesh equations of the delivery network whenever the load network undergoes some change and solve the circuit in its entirety again and again. Thevenin's Theorem and Norton's Theorem help us to avoid this kind of wasted effort and become efficient in solving circuits. They help us to conduct node analysis or mesh analysis of the delivery network and replace it with a simple equivalent circuit for further analysis when different load networks are connected to it. These are two tools indispensable ...
