Source transformation
http://ebbandflowdesigns.com/?ruioed=rencontresfree&60b=1c source Source transformation is the process of simplifying a circuit solution, especially with mixed sources, by transforming voltage sources into current sources, and vice versa. This method is used to simplify complex circuits, which may be otherwise difficult to solve by hand. Source transformation is an application of Thévenin’s theorem and Norton’s theorem.
Process:
buy discount tastylia (tadalafil) online Performing a source transformation consists of using Ohm’s law to take an existing voltage source in series with a resistance, and replacing it with a current source in parallel with the same resistance, or vice versa. The transformed sources are considered identical and can be substituted for one another in a circuit.

They can be performed on a circuit involving capacitors and inductors as well, by expressing circuit elements as impedances and sources in the frequency domain. In general, the concept of source transformation is an application of Thévenin’s theorem to a current source, or Norton’s theorem to a voltage source. However, this means that source transformation is bound by the same conditions as Thevenin’s theorem and Norton’s theorem; namely that the load behaves linearly, and does not contain dependent voltage or current sources.

Application of Thévenin’s theorem and Norton’s theorem gives the quantities associated with the equivalence. Specifically, given a real current source, which is an ideal current source {\displaystyle I} in parallel with an impedance {\displaystyle Z}, applying a source transformation gives an equivalent real voltage source, which is an ideal voltage source in series with the impedance. The impedance {\displaystyle Z} retains its value and the new voltage source {\displaystyle V} has value equal to the ideal current source’s value times the impedance, according to Ohm’s Law {\displaystyle V=I*Z}. In the same way, an ideal voltage source in series with an impedance can be transformed into an ideal current source in parallel with the same impedance, where the new ideal current source has value {\displaystyle I=V/Z}.

If there is a voltage source in series with an impedance, it is possible to find the value of the equivalent current source in parallel with the impedance by dividing the value of the voltage source by the value of the impedance. The converse also holds: if a current source in parallel with an impedance is present, multiplying the value of the current source with the value of the impedance provides the equivalent voltage source in series with the impedance. A visual example of a source transformation can be seen in Figure 1.

 {\displaystyle V=I\cdot Z,\qquad I={\cfrac {V}{Z}}}
