BASIC ELECTRICITY - PART 1
The objective of this and the following few readings is to introduce the beginner to
the basic concepts of electricity and provide some revision for the more advanced
reader. It is extremely important to have a thorough understanding of the
fundamentals of electricity before any study of radio munications. You may
be surprised to know that many 'professionals' have a significant lack of
understanding of the very basics of electricity. I think this is because you can
actually get by without it; however this lack of basics makes understanding of more
complex theory difficult and uninteresting.
ELECTRICITY
plicated electronic systems involved in modern-munication,
satellites, nuclear power plants, radio, and television, and even up-to-date
automobiles, does not really require technicians to understand the functioning of
electric and electronic circuits. Modern day electronics is very modular. A remove
and replace, or substitution of the suspected 'faulty module' is generally the
approach to modern electronics servicing. This, in itself is not a bad thing, as in the
real world, getting an electronic device up and going is the most important thing.
However, to have a true understanding, requires a strong foundation in the basics
of electricity.
