# Linear and Nonlinear Circuit Elements

One of the major goals of this unit is to develop expressions for electric field intensity E and electric potential, which may be shortened by the term Voltage V.

Let’s continue from the results of Coulomb’s experiment on the electrical force between charged bodies. An isolated charge Q induces an electric field E at every point in space, and at any specific point P, E is given by

In the presence of an electric field E at a given point in space, which may be due to a single charge or a collection of many charges, the force acting on a charge Q, when the charge is placed at that point, is given by
