Page Index For Circuits

These pages are mainly intended as supplementary for students pursuing electronics or related subjects. It is not the intention to repeat the explanations that can readily be found in books, but to supplement them with visual interactive illustrations of some of the concepts that students find difficult at first encounter. Most of these illustrations are done with java applets and pages are best viewed with a java enabled browser. The applets were originally written to be projected onto a screen during lecture/demonstration and have been tested with a 3GHz PC with Windows XP. With early versions of WinXP the Java virtual machine must be downloaded from Sun Microsystems. Later releases of WinXP and Windows Vista block Java applets(This is the continuing saga of Microsoft trying to bring an end to Java). The following message appears: "To help protect your security, Internet Explorer has restricted this file from showing active content that could access your computer. Click here for options..." . To see the applets here active content must be unblocked. The applets only interact with the screen. Some sample GIF files of the applets are shown.
