Finding'''Source atransformation''' solutionis tosimplifying a circuit can be somewhat difficult without using tricks or methods that make the circuit appear simpler. Circuit solutions are often simplifiedsolution, especially with mixed sources, by transforming a voltage into a [[Electric current|current]] source, and vice versa.<ref name="Oppenheimer">Oppenheimer, Samuel L.

Source transformation is an application of [[Thévenin's theorem]] and [[Norton's theorem]].
