SUBCOURSE 308, INTRODUCTION TO ELECTRICITY
INTRODUCTION
Ben Franklin's experiment with a kite opened up a whole new way of life to
later generations. As a result of this experiment, we have a world that has become
dependent upon electricity.
Almost all major industries lean heavily upon
electricity to run their factories; radio, telephone and telegraph communications
operate with electricity; medicine depends upon electricity for X-ray and diathermy
equipment, various pumps, cooling and heating devices; homeowners use electricity
to both heat and cool their homes, preserve food, run dishwashers and irons, and
various entertainment devices; our homes and highways use electricity for lighting;
ships, planes, trains, buses, and cars all require electricity to operate.
Of course, all these things that are so much a part of our lives must be
maintained and repaired.
This subcourse is designed to teach you electrical fundamentals, which is the
basis for repairing any electronic equipment.
This subcourse consists of one lesson, the lesson exercises and the subcourse
examination.
