Can some one explain Electric flux to me. I know it is suppose to measure the flow electricity but why is flux indepenent of area size?

You must be referring to some special geometrical situation. In general, the flux will ratio with the area... see the diagrams half-way down this page, for example:

http://en.wikipedia.org/wiki/Electric_flux

The "flux density" will not change with area, however. Is that what you are asking about?

Or are you referring to the fact that the total flux from a point charge is the same as you go out through concentric spheres, farther and farther away from the point charge?
