Illustrations that I have added to Wikimedia Commons and inserted in some articles:
Illustration of the electric field surrounding a positive (red) and a negative (green) charge (click for larger image). I inserted this illustration in the Electric field article.
Illustration of the electric field surrounding two equal charges (click for larger image).
Illustration of the electric field surrounding one positive charge (click for larger image). I'm not quite satisfied with this one, but I don't see any article where it would be obvious to use, so I won't improve it just now.
References (or refs), on Wikipedia, are important to validate writing and inform the reader of the source of the text. When adding something to an article, it is highly advisable to cite a reference which describes the source of the information to help the reader who wishes to verify it, or to pursue it in greater depth. It is also useful to update or improve existing references.
