There are certain formulas in physics that are so powerful and so pervasive that they reach the state of popular knowledge. The predominant equation which pervades the study of electric circuits is often referred to as the Ohm's law...

More than a dry series of facts about Ohm's life, this page from the University of St. Andrews provides interesting anecdotal accounts which reveal the personality behind the man. Thorough, interesting and an abundance of facts. A great...

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.

When two or more electrical devices in a circuit can be connected, it is considered a series connection or a parallel connection. When all the devices are connected using series connections, the circuit is referred to as a series...

A teacher lesson plan which could be easily converted into an idea for a student project or presentation. This page describes an activity in which the water-electricity analogy is used to investigate the relationship between current,...

Electrical currents and voltage are defined and illustrated.

At this site from Georgia State University parallel and series connections of resistors are explained and illustrated. Equations for computing the overal voltage, current, and resistance of such circuits are given and explained.
