Instructional Objectives

A. By the time of Exam No. 1 (after 13 lectures), the students should be able to do the following:

• Use Lorentz force equation to calculate the electric and magnetic fields in a region for a specified set of forces on moving charges, use Coulomb's or Gauss' Laws to calculate the electric field due to a charge distribution, apply the same principles in reverse to design a charge distribution that produces a specified electric field (1,2)
• Calculate the electrical potential of curl-free static electric fields using Poisson's or Laplace's equations, understand the lumped circuit voltage concept in terms of potential differences of quasi-static fields surrounding compact circuit components (1)
