MODEL: Charged particle and its field
Model: Parallel Charged Plates and their Uniform Electric Field
Finding the strength of an electric field from the gradient (rate of change with respect to position) of its potential: (We won't worry about the sign of the slope, just its magnitude. How strong the field is doesn't depend on its direction. For you experts, physicists put a "minus" sign in the relationship below the graph just to account for the direction of the field.) MODEL: Electric Dipole
Ways to represent electric fields
Electric field lines representing the electric field of a dipole (above)
Dipole potential on the xy plane as seen at an angle
Dipole potential on the xy plane as seen from straight above
Boundaries between colors are equipotential lines. What is the angle between field lines and equipotentials? Model: Atomic model for gases

Chapter 17 Objectives
Order of reading in Chapters 16 and 17
We will first consider electric forces, electric charge, electric fields, and electric potential energy in general. Then we will consider the special and important case of electrically charged particles. Finally we take a look at a very important component of electric circuits, namely capacitors. That's the reason for the following arrangement of our course of study.
