WebThe flux Φ of the electric field →E through any closed surface S (a Gaussian surface) is equal to the net charge enclosed (qenc) divided by the permittivity of free space (ε0): Φ = ∮S→E · ˆndA = qenc ε0. To use Gauss’s law effectively, you must have a clear understanding of what each term in the equation represents. WebFeb 2, 2008 · 65. 0. My textbook (high school level) derives an instance of Gauss's Law with Dielectric for the case in which the dielectric material fills the gap between a parallel-plate capacitor entirely. So you get surface int (D dot Area-vector) = q, where D = (dielectric constant) (epsilon_0) (Electric field), and q is the free charge (on capacitor)
