4.2: Source Transformation

SOURCE TRANSFORMATION

Process of replacing a voltage sources and current sources as follows:
1. Replace voltage source (Vs) in series with a resistor (Rs) by a current source (Is).
2. Replace current source (Is) in parallel with resistor (Rs) by a voltage source (Vs)
3. Two or more parallel current sources can be summed and represented as one current source.
4. Two or more series voltage sources can be summed and replaced with one voltage source.

Example:
For the circuit below use source conversion to simplify the circuit as much as possible and calculate RL that results in maximum power transfer.
