What does the flux of a vector field measure?
The flow or penetration of the field vectors through a surface
For a uniform electric field normal to a surface of area A, what is the flux?
$A$
How is the electric field at any point on a sphere with charge at its center directed?
Radially outwards
What happens to the total electric flux leaving a closed surface when the charge enclosed by the surface increases?
The flux increases
