Lecture 6 Outline of Last Lecture I. Electric Flux (Φ) = EAcosθ II. Gauss’ Law: the electric flux through a closed surface is proportional to the net charge enclosed by the surface a. Σ E cosθ ΔA = qenc/ε0 b. ε0 = permittivity of free space = 1/4πk = 8.85 x 10-12 C2/(N*m2) c. E changes depending on where q is on the surface, but electric flux stays the same d. Charges outside of the surface will not change electric flux e. σ = surface charge density = q/A f. ex) Spherical symmetry g. ex) Infinite plane of charge PHYS 012 1st Edition
