First we solve for the electric potential along the axis of a uniform thin ring of electric charge. Then we use that electric potential to solve for the electric field at the same location.

The electric potential difference in a uniform electric field is derived and used to show lines of equal electric potential or equipotential lines. Equipotential lines and surfaces of point charges and dipoles are shown. The equation for...

Conservation of energy is used to determine the final speed of a proton released at rest in a uniform electric field.

Calculus is used to derive the equation for the electric potential difference between two parallel plates of equal but opposite charge. It’s a uniform electric field. The significance of the negative in the equation is explained.
