Electrical Systems

APPLET website, covering everything from basics to extreme. VERY USEFUL!!! http://www.falstad.com/circuit/e-index.html


Nice interactive visual display of a circuit showing Ohm's law and the effects of changing current/voltage/resistance etc. http://micro.magnet.fsu.edu/electromag/java/ohmslaw/


Great visualisation of a motor to explain the right hand rule and magnetic forces created in a current carrying wire; http://www.walter-fendt.de/ph11e/electricmotor.htm


Comprehensive site that seems to cover most topics in basic electrical systems, with well explained examples and exam style questions: http://www.gcse.com/electricity.htm
