A simple circuit simulation of an LED, current limiting resistor and power supply

This makes use of the excellent Javascript circuit simulator from

Notice that you can move the mouse over any part of the circuit and it will show you the voltage ("Vd=") and current ("I=") at that point in the bottom right corner.

There is also a version which uses Falstads older Java circuit simulator. Java, which is available for most operating systems and browsers from is no longer commonly supported in Browsers due to security concerns.
