This document discusses electrostatics and electric potential through 5 sample problems. It outlines the general steps to take in solving for the electric field or potential. These include: 1) writing the equation, 2) determining charge density, 3) substituting the charge element, 4) integrating, 5) substituting total charge density, and 6) plugging in ranges and simplifying. The document explains how these steps remain the same but the specifics change depending on the geometry and properties of the situation.
