I have changed this section so that people familiar with electrical components and calculations will feel more at home (possibly!). The idea is that you can now express component values, such as resistance with a familiar suffix, i.e 10 Megohms = 10M and can be input as such. Here are the standard suffixes (suffices??) for SI units. Table of Common SI AbbreviationsThere are other units, such as "Exa", which I didn't include. Confusingly, you will see resistors marked 1e5 or 1r5, meaning 1.5 Ohms. If you enter 1e5 into the edit box, it will be interpreted as 1.5 (Try it) BUT if you enter 1E5  the program will think you are using eponential notation (Try it). 1r5 DOES NOT WORK  it is the old way of marking resistors. Note that you can enter 1M8  meaning 1.8Meg(Ohms or whatever).
Try BoxThings that are not physical quantitiesThings like turns ratios an numbers of turns are just arbitrary numbers  and enter them as such. You can enter them with the above suffixes. I suppose a kiloturn is a thousand turns, but they will be output as numbers in scientific notation. Why do it?I am trying to make the input follow consistent rules, reduce typing and mimic the values printed on the components. You may find other programs like ltSpice follow similar input rules. The section is (possibly unfairly) targetting engineers and engineering students, as well as hobbyists with an engineering background. Let me know how you get on. The equations in the "theory" sectionWith the exception of the reactance chart, the equations are generated by jsMath, a mathematics text processing system. I would have liked to use MathML, but I can't get Internet Explorer to decipher it. jsMath puts a red banner at the top of the section, inviting you to download fonts. It still works (more slowly) if you don't download them. Source CodeIs available. Contact me, as the source may not be available from the "view source code option" in your browser.
