Perspective from the instructor:
PURPOSE: This
course will introduce you to the basics of electric phenomenon and
hopefully you will obtain enough understanding of the principles
thereof to allow you to deal intelligently with electrical problems
encountered in personal and professional life.
Overview of E & M Our entire tirade this quarter is
based upon the idea that an electron is a small distinct object
having not only a fixed mass and fixed dimensions, but a fixed
amount of something called charge as well. In fact, we will assume
that this is the only moveable object in the universe that contains
charge !(Protons contain a positive charge equal to and opposite the
charge on an electron, but they will always be embedded inside
nuclei of atoms.)
Therefore, all our explanations of
electricity, mine to you and yours to me, will be in terms of the
motion of electrons, and nothing else!
Actually, charge is more a condition than an object. Although
Milliken measured the mass of an electron, and many have determined
its charge, efforts to actually see an electron have resulted in
seeing a cloud with bumps in it.
The charge on an electron is -1.6x10-19coulombs, whatever that is,
and its mass is 9.11x10-31kg. The charge on a proton is
+1.6x10-19coulombs, and its mass is 1.67x10-27kg.
The driving force of all of our discussions will be the electric
force between charged objects, namely,
Coulombs law: FE of q1 on
q2 = kq1q2/r2 , where r is the distance between q1 and q2.
First, Static Electric force-
Force due to stationary charges embedded in an insulator.
Second, Electric Potential
caused by an object containing charge, (Voltage), exactly like the
gravitational potential due to the force of gravity caused by a body
containing mass.
Third, we'll look at what
happens when we allow these little charged particles to run around
loose inside a conductor. When a bunch of them are running in the
same direction at a steady rate, we call this phenomenon Current, in
Amperes, obviously, which actually represents coulombs per second.
Fourth, We'll look at the
behavior of these little critters when they are driven by an
electric potential of a battery to run around in a bunch of
conducting wires all connected together (DC circuits).
Fifth, we'll take an
apparent sidestep to examine Magnetism, but soon we'll return when
we discuss the connection between Magnetism and Electricity, and
finally, we'll discuss what happens when electrons are driven by a
spinning magnet in an AC generator, or
Sixth, AC circuits, which
will lead to the discussion of a funny frustrated little critter
called an inductor. He's always frustrated because when you try to
push electrons through him, he gets mad and tries to stop you. Then
if you try to stop pushing electrons through him, he gets just as
mad and tries to drag them through anyway.
Note: We have 16 class
days, (three of which I will miss but you won't), and 4 test days.
The following schedule is driven by this fact and the course
syllabus. Note: Quizzes are due at 11:59 PM on the day assigned.
