Intro to Electric Flux & Gauss's Law

An introduction to electric flux, the area vector, and Gauss's Law.

0:00 - Intro
1:36 - Flux and what affects flux
2:38 - The area vector
3:58 - Positive vs. negative flux
6:05 - Sign of flux on a cylinder
12:02 - Using Gauss's Law to make it easier

Important Points:
- The area vector is a vector that is normal (perpendicular) to the surface area it describes.
- Electric flux can be positive, negative, or 0 depending on how the area vector and electric field vectors are aligned.
- Gauss's Law states that the electric flux through a closed surface is equal to the total amount of charge enclosed by the Gaussian surface divided by the permittivity of free space.

Where we would be without Gauss? I, for one, wouldn't hold two electrical engineering degrees!
