The
Schematic Workbook
- In
the electrical and electronic industry. a schematic diagram is often
used to describe the design of equipment. Schematic diagrams are often
used for maintenance and repair of electronic and electromechanical
systems.
- Electricity is essential
for light,
power, air-conditioning, and refrigeration. Electricians install and
maintain electrical systems for a variety of purposes, including
climate control, security, and communications. They also may install
and maintain the electronic controls for machines in business and
industry. Although most electricians specialize in either construction
or maintenance , a growing number do both. You must have knowledge of
Ohm's law and theory, before you can successfully troubleshoot
electrical equipment. However, unless you know how to apply Ohm's Law
and theory, and make tests, your knowledge is useless. Theory and
practical application must go hand-in-hand.
-
It is extremely important for you to become familiar with the various
symbols used. You will have to use this type of diagram throughout your
career, because manufacturers of electrical equipment seldom supply a
pictorial diagram, it is far easier to work from a schematic once you
learn how to use it.
-
Start first with simple schematics, and gradually work up to
more complex ones. In time, you will be as much at ease reading reading
a complex schematic diagram as you are reading your newspaper. You will
soon learn the value of this type of diagram and see how much easier it
is to use than the pictorial type.
-
Symbols commonly used to represent resistors, capacitors,
and ground connections.
