### Thevenin Theorem

1. Understand the importance of Thevenin’s theorem.
2. Draw Complex Network into a Thevenin’s equivalent circuit.

It is possible to reduce a complex circuit to a single voltage source and series resistance connected to a load.

Steps:
2. Remove the Load Resistance R$_L$.
3. Calculate/measure the open circuit Thevenin’s voltage V$_{TH}$ across two open ends.
