The good news is that in ELEC 243 laboratory, you will not be exposed to dangerous voltage levels unless you mishandle the equipment. Before we get close enough to the equipment to mishandle it, let's take a closer look at just how you can get hurt if you do.
Electricity is potentially the most dangerous commodity in general use by the public today.
In spite of this, less than 1 percent of the 100,000 accidental deaths which occur annually in the United States are directly attributable to electrocution. Considering the ever-increasing use of electricity in the home and industry, we should be alert to protect and better this excellent safety record. An understanding of the effects of electric shock, high-frequency heating, and other electrically produced physiological phenomena on the human body should be part of basic knowledge. We present a brief survey of these topics in the hope that you will become aware of the very real dangers inherent in the application of electrical phenomena. We shall consider these dangers in each frequency band of the electromagnetic spectrum - from the power frequencies to cosmic rays.
