Intro to Electric Fields: LD Industries Physics 30

Maybe you're heard your Physics teacher talk about Fields a lot lately...but what is a field, and what are they even used for? In this video, Brad takes you through the basics of electric field theory and gives you some pointers on how to model electric forces with uniform and non-uniform electric fields.
Also included is a cameo by Dash the cat.

I came for the cat vs balloon action, I stayed for the electric field lines.
