An Australian consulting company maintains this valuable Internet resource for electrical engineers. Many theorems and formulae are included, ranging from fundamental voltage and current laws to transformers and three-phase circuits. The site lists common practices for reducing circuits into simpler representations, which facilitates the process of circuit analysis. Anyone who designs or evaluates analog circuits can benefit from the material, and engineering students can make use of the site by printing each page as a quick reference sheet. Unfortunately, no diagrams accompany the discussions, and this is one area in which the site is clearly lacking.
