Explains what a combination circuit is, reviews the features of series and parallel circuits, and demonstrates how to analyze combination circuits. Includes detailed examples and some problems for students to try. There is also a link to...

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

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.

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.
