Curated OER
How a Capacitor Works
A capacitor stores energy in the form of an electric charge. See a circuit diagram explaining charges and electron flow. Equations are given for energy and a capacitor is made. Show this to your physics or beginning electronics class.

Introduction to Electricity
A sleepy-sounding narrator teaches about moving electrons, accompanied by video and simple computer animations. He explains what a circuit is, what voltage means, and what current and amperes are. Throughout the video, safety tips for...

Electrical Circuits: Voltage
Voltage in relation to electrical circuits is the topic of this clip. First potential energy is explained in terms of gravity, then the idea is conveyed to describe how the chemicals in a battery act as potential energy for an electrical...
Curated OER
Voltage and Current, Part 2
Second in a two-part lesson on electricity, this video explores how voltage sources can be applied to create electron flow in a circuit. Though it is not modern or high-quality, it is educational. Used with part one, it can sufficiently...
Curated OER
Voltage and Current, Part 1
First in a two-part series, this video is comprised of diagrams, pictures, and animated images explaining how an imbalance of electrons causes them to move. Stored electric charge is revealed as potential energy, and a water tower...
