This comprehensive tutorial site provides an overview of electrostatics, complete with simple demonstrations, labs and extensions for both the student and the teacher. Topics covered include charge, charge transfer, electric force, and electric field. The unit includes excellent questions at the end of sections that check for student understanding. Students usually find electrostatics to be difficult and abstract. Static charge distributions and their resulting electric fields cannot be seen, yet these invisible quantities can exert strong forces on nearby charges. This tutorial is written in simple language and is filled with analogies and examples designed to help the student visualize electric charge, electric force and electric fields. Simple demonstrations and labs help make the concepts, which are inherently abstract, more concrete and approachable. Checks for understanding allow the student to identify and correct misconceptions.
