Source Transformation
Source transformation is the process of simplifying a linear circuit, especially with mixed sources, by transforming independent voltage sources into independent current sources using Norton's theorem, and vice versa using Thévenin's theorem . The process is usually combined with series and parallel simplifications of resistor (or impedance in the case of AC circuits), current sources and voltage sources.
Conversion from Norton to Thévenin equivalent circuit
When transforming a circuit from a Norton equivalent circuit to a Thévenin equivalent circuit the value of the resistance remains the same, while the voltage of the voltage source is $$\begin{equation}V=R I\end{equation}$$
Conversion from Thévenin to Norton equivalent circuit
When transforming a circuit from a Thévenin equivalent circuit to a Norton equivalent circuit the value of the resistance remains the same, while the current of the current source is $$\begin{equation}I=\frac{V}{R}\end{equation}$$
