### Wikiquizzes[edit]

**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.**Q:UsingGaussLaw**is a wikiquiz that applies Gauss law to spherical, cylidrical and planar geometries

### Readings[edit]

**Physics equations/Electrostatics**reviews material useful for the algebra based wikiquizzes**Physics_equations/Capacitors**explains how capacitors work

##### CALCULUS based readings[edit]

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.
