Lightning strikes on airplanes are not as rare as one might think. In fact, almost every commercial jet is struck by lightning at least once a year! There is a good chance that you’ve been in one when it was struck by lightning; you...

First we solve for the electric potential along the axis of a uniform thin ring of electric charge. Then we use that electric potential to solve for the electric field at the same location.

The work to move a charge through a uniform electric field is determined. An electron volt is defined.

In this video, we learn about electric fields and the electric force between charged objects. We see how a charged comb can create an electric field that attracts nearby pieces of paper. This video is part of the 9-part series, Electricity.

This video describes the basic role that atoms play in creating electrical charges, as well as the nature and creation of static electricity. Various methods of charging are discussed, emphasizing the role that insulators and conductors...

Electricity makes our lives easier every day. We use electricity in our work and play. Because electricity is virtually unseen, it is often difficult to understand just where it comes from and how it works. By watching the video and...
