... The electrical energy that can actually cause injury is due to electrical current and how it flows through the body. Why, then, does the sign warn of high voltage? Because of the way electrical ... under- standing of electrical engineering. Before we can examine this aspect of electrical safety, we have to learn how voltages and currents are produced and the relationship between them....

... Perspective Electrical Safety At the beginning of this chapter, we said that current through the body can cause injury. Let's examine this aspect of electrical safety. You might think that electrical ... level is not the sole RSPECWE determinant of potential injury due to electrical shock, consider the case of a static electricity shock mentioned in the Practical Perspective at t...

... After introducing the techniques for analyzing the natural and step responses of first-order circuits, we discuss some special cases of interest. The first is that of sequential switching, ... that is, we have a natural-response problem. RL and RC circuits are also known as first-order circuits, because their voltages and currents are described by first-order differential equation...

... of this example, it is important to point out that safety analysis is an essential part of an electrical engineer's work. Now that we have modeled the controls for the hair dryer, let's ... Recall from Chapter 4 that certain systems—for example, those that trans- mit information via electric signals—depend on being able to transfer a maximum amount of power from the source to

... Distribution of Electric Power In this chapter we introduce circuits that are designed to handle large blocks of electric power. These are the circuits that are used to transport electric power ... considering only balanced circuits. The analysis of unbalanced three-phase circuits, which you will encounter if you study electric power in later courses, relies heav- ily on an u...
