# Flux's Law Concept Question

## Main Question or Discussion Point

I'm currently trying to understand the concepts behind electric fields, flux, and Gauss's Law, so I'd appreciate it if someone could clear some things up for me.

Flux is the amount of field lines that pass through a surface, so if there's a uniform electric field, will the net flux through any object will be 0?

Almost! If I'm not mistaken, Gauss's Law tells us that the flux through a Gaussian surface will only equal zero if there is no charge located within the surface. So, so long as your surface does not contain the charge creating the uniform field, then your current assumptions lay correct.

Thanks for the help.
