1. Source Transformation
Convert a Voltage Source
in Series with a Resistance into
A Current Source
in Parallel with the SAME Resistance
And vice-versa
ECE 201 Circuit Theory I

2. Source transformation
Convert the voltage source in series with R into an equivalent current source in parallel with the SAME R!
And vice-versa.
ECE 201 Circuit Theory I

3. How to make them equivalent
Attach a load resistor (the same one) to each circuit, and ensure that each circuit delivers the same voltage and current to the load.
