Hello,

I am an inspiring Electrical Engineer, and would like to contribute to this stub. If anybody has any suggestions or comments, please feel free to message me. Perevodchik (talk) 23:27, 26 February 2008 (UTC)

## DC source and Z in image?

It is inconsistent to have DC source and an impedance (Z) in image.Cblambert (talk) 01:58, 3 February 2013 (UTC)

## SOURCE TRANSFORMATION

Source Transformation can be done by changing voltage to current source and vice versa. For changing voltage to current source-

```                                        [I=V/R]
```

For changing current to voltage source-

```                                        [V=I*R].  — Preceding unsigned comment added by 101.59.82.179 (talk) 16:21, 29 March 2016 (UTC)

Edited for clarity of wording. Modified the Process section to include an introduction on the use of source transformation, a paragraph on the use cases and limitations of source transformation, and then a description of the mathematical process of source transformation.

## Proof of the theorem

I am thinking of adding the following brief discussion on the proof of the theorem. By the way, I don't tend to think the transformation is an application of an application of Thévenin's theorem and Norton's theorem. In fact, to proof those theorem, one needs a good notion of the source transformation beforehand.

### A brief proof of the theorem

The transformation can be derived from the uniqueness theorem. In the present context, it implies that a black box with two terminals must have a unique well-defined relation between its voltage and current. It is readily to verify that the above transformation indeed gives the same V-I curve, and therefore the transformation is valid.
