Wikipedia offers detailed information on capacitors, including a hyperlinked table of contents for easy site navigation.

A capacitor is similar to a battery in that both store electrical energy. But a capacitor can't actually produce new electrons; it only stores them.

This article from Khan Academy provides information about capacitors. This information is intended for the Class 12 Physics Course (India).

An entire book on electrolytic capacitors. Originally published 1938 and website version is an in-progress update. Part 1 is sufficiently general and current to give one a background in capacitors and electrolytic capacitors.

In this simulation a battery will be used to charge a capacitor. The capacitor will then be used to operate a light bulb until the capacitor is discharged.

Online university physics text called "Hyperphysics". Three sections here: Capacitors, Capacitor Combinations, Charge on Series Capacitors. These are nice clean lessons, good illustrations, many hotwords to assist. A fine online lesson,...

This lab is designed to have students investigate the factors that affect the rate at which a capacitor charges. Students can change the resistance and capacitance in the circuit and monitor the current, voltage and charge on the...

A simulation investigating a parallel-plate capacitor which is charged by connecting one plate to the positive end of a battery, and the other plate to the negative end. The battery sends electrons from one capacitor plate to the other...

Determine the total energy stored on a group of capacitors in a combination circuit.

Text and animated graphic show how lightning is an example of a natural capacitor.

Determine the time it takes an electron to reach a phosphorescent screen when it is fired by a capacitor. Students must also find the top speed of the electron and the amount of vertical deflection it experiences.

Determine the time it takes an electron to reach a phosphorescent screen when it is fired by a capacitor. Students must also find the top speed of the electron.

This lab is designed to have students investigate the different changes that could be made to an air filled capacitor and the results that occur because of these changes. Students can vary the gap between the plates, the size of the...
