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.

Learning about charge and forces of attraction will be keys to understanding electrostatics and the basis of this learning unit. Developing a greater understanding of charge and the charge model is necessary to understanding electricity.

[Free Registration/Login may be required to access all resource tools.] Students learn which subatomic particles contribute to static electricity, and determine the charge of an object based on what particles it has gained or lost.

Learn about conductors and electric fields in static equilibrium.

The National Grid is a high-voltage electric power transmission network, connecting power stations and 340+ substations ensuring supply and demand is in the balance. Nigel Williams speaks to Robert Llewellyn about how the National Grid...

Luigi Galvani was a pioneer in the field of electrophysiology, the branch of science concerned with electrical phenomena in the body. His experiments with dissected frogs and electrical charges led him to suggest the existence of a...

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

These devices, though quite humble, represented a tremendous breakthrough in the history of electricity; they were the first capacitors, and as such were able to store electric charge. (Java tutorial)

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...

This instructional activity introduces the concept of electricity by asking students to imagine what their life would be like without electricity. Two main forms of electricity, static and current, are introduced. Students learn that...

Peter Debye carried out pioneering studies of molecular dipole moments, formulated theories of magnetic cooling and of electrolytic dissociation, and developed an X-ray diffraction technique for use with powdered, rather than...

An experiment to find out how an old-style doorbell works.

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...

[Free Registration/Login may be required to access all resource tools.] Students investigate how electric force, charge, and distance all relate to each other in Coulomb's Law. Presents Coulomb's Law, the SI unit for charge, the...

The legendary Lord Kelvin made electricity from water with this ingenious electrostatic generator. (Java tutorial)

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...

It may look like a simple black blob, but an oil drop is in fact a phenomenally complex mix of immense molecules called hydrocarbons. Using a type of mass spectrometry called FT-ICR, scientists can analyze oil and other macromolecules...

Experiment with the torsion balance and see what happens first by giving the rod a charge, and then by moving the charged rod closer to the outer metal sphere of the instrument. Observe what happens to the needle as the charge increases.

Theoretical physicist Julian Schwinger used the mathematical process of renormalization to rid the quantum field theory developed by Paul Dirac of serious incongruities with experimental observations that had nearly prompted the...
