Explore how a capacitor works! Change the size of the plates and add a dielectric to see how it affects capacitance. Change the voltage and see charges built up on the plates. Shows the electric field in the capacitor. Measure voltage...

Electric circuits are used to provide a path to electric current. They commonly use three basic electrical components, which are resistors, capacitors, and insulators. They affect the electric current and changes the behavior of the...

This resource explains how an electrical field is created and the criteria that determines its' strength. Other topics briefly addressed include capacitors and the work of Michael Faraday.

Everything you need to know about how Leyden jars work, and how to construct your own. Many pictures, references, other sites, other electrostatics projects and topics.
