Pictures and commentary:

Speaking of pictures ... film versus digital.

Go Canes!

Remember to keep track of your units!

The pair of Van de Graaffs in the Theater of Electricity at the Boston Museum of Science.  A similar device, the Cockcroft-Walton, at Fermilab.

The electron gun at SLAC, near Stanford University.

Caltech has some useful "applets" on-line, one of which draws
electric field lines, and potential contours.

A few capacitors in a circuit.  Another "layered" device, a simple transistor.

Hoover dam (informally known as Boulder dam) viewed from space, and what R P Feynman had to say about it and Faraday's law of induction.

Information about the ubiquitous plasma globe.

Some of the world's most powerful (not self-destructing) magnets (~50 Tesla) may be found at The National High Magnetic Field Laboratory located at Florida State University.

Movies and commentary:

A brief explanation of how a Van de Graaff works.

Tesla coils are another source of entertaining high voltage effects (see here and here).  But, like natural lightning, they can be very dangerous (see here)!  Therefore we will NOT use them for in-class demos.  The closest you probably want to be to a Tesla coil is while viewing these movies: Tesla1, Tesla2, Tesla3.  Many other web pages dealing with Tesla coils can be found on the internet, for example, by using the Yahoo! search engine.  I recommend that you enjoy the pictures, but let it go at that.

The Aurora is described at several sites.  I especially like the information provided by the University of Alaska which includes video clips.  Also note the Northern Lights Planetarium in Norway, from which I have taken this video.

Here is a JAVA applet which simulates an RLC circuit containing a battery.

Here is a JAVA applet which simulates an electro-magnetic sine wave.
