I spent about an hour working with the applet, which allows the user to build a variety of series LRC circuits and observe the transient behavior. The applet is rather well done, and qualitatively and quantitatively illustrates the physics of this class of series circuits rather well. It has an unusual display, showing the voltages at the nodes by tilting the circuit. This is clever, but probably will need to be explained to most students. The display of (t,V) points would be more quantitatively useful if it showed only the actual values of V for a given t, and only when the mouse pointer is close to the plotted voltage curve. As is, the graphs are hard to see on the gray background, and cannot be used for consistent quantitative measurements.Technical Remarks: The major problem is that the calculations are unstable for some values of circuit elements and time scales.
