Wikiquizzes

• Q:KE&PE is a wikiquiz that uses energy conservation and the relationship between electric potential, V, and electric potential energy, U = qV
• Q:capacitance is a wikiquiz that uses basic facts about capacitors and electric energy density.

 CALCULUS based wikiquizzes

• Q:SurfaceIntegralsCalculus integrates a vector field over the surface of a cylindar centered at the origin.
• Q:MoreGreenlikeSourceIntegrals is a wikiquiz that further examines how vector integration is used in field theories.

CALCULUS based readings

As a supplement to Chapter 18 we showed how Coulomb's Law can be integrated using vector calculus. Here we extend this understanding of vector calculus.

• Coordinate_systems introduces calculus in three dimensions
• Vector calculus further explores calculus in three dimensions and extends the fundamental theorem of calculus into higher dimensions
• b:Electrodynamics/Gauss's_Law shows how vector calculus allows us to quickly find the electric field geometries made simple by high degrees of symmetry.
