In this video segment adapted from ZOOM, cast members show you how to make your very own electroscope. You can use it to find out if an object is electrically charged. [4:17]

In this learning module, students will observe interactions between objects, including objects with electric charges to identify patterns in how things interact.

This unit teaches students the foundations of electrical circuits and introduces them to their simplest components. Covers series and parallel circuits, Kirchhoff's Rules, Ohm's Law, RC circuits, resistivity, and capacitance.

Defines electric potential, field lines, and equipotential lines. Contains example problems and formulas for solving.

Learn about conductors and electric fields in static equilibrium.

From the ESD Journal website. This page describes the industrial and medical risks associated with the buildup of static charge. The investigation of the electric potential created by such accumulated charges and the materials...

A large complete authoritative biography of Coulomb. Five large pictures, over a dozen links to contemporaries, references, a poster, other mathematicians. A fine source.

This site from the Georgia State University explains the concept of electric potential about a point charge or combination of severat point charges. An interactive JavaScript form allows the visitor to investigate the effect of distance...

Although specifically designed for physics students at Caltech, anyone interested in learning more about electricity, magnetism or various other physical phenomena can benefit by exploring these interactive applets. A circuit tutorial...

Electrical currents and voltage are defined and illustrated.

Because they could store significant amounts of charge, Leyden jars allowed scientists to experiment with electricity in a way never before possible.

Joseph John Thomson, better known as J. J. Thomson, was a British physicist who first theorized and offered experimental evidence that the atom was a divisible entity rather than the basic unit of matter, as was widely believed at the...

College-level electrical engineering textbook starting from the Coulomb-Lorentz force law on a point charge. Sample problems that reinforce the content are found at the end of each chapter. Includes downloadable excerpts of the textbook...

Charles-Augustin de Coulomb invented a device, dubbed the torsion balance, that allowed him to measure very small charges and experimentally estimate the force of attraction or repulsion between two charged bodies. The data he obtained...
