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.

[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.

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...

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

[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...

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...

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...
