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
