Introduction Excerpt

Electrical and electronic equipment and devices play an integral part in our daily activities, both in the home and in industry. The use of electricity is very convenient but can also be deadly if it is not properly handled. In practice, simple mistakes can have serious consequences and may cause severe damage, injuries, or even loss of life The study of electrical and electronics technology involves a lot of theories which are often applied in interrelated ways. Further, mastering the subject matter both theoretically and practically requires some level of competence in analysis and synthesis. In simple terms, analysis has to do with finding out how a given circuit or system will respond, and the output it will produce. Synthesis. on the other hand, has to do with designing a circuit or system that will respond in a particular way and produce a desired output. In studying electricity and electronics, problem solving is an indispensable skill. In order to get a firm understanding of the theoretical material, it is often necessary to solve numerical problems. Moreover, the solution of problems helps in memorizing laws and formulas. Knowing how to use a scientific calculator is equally as important, especially since most of the functions available and the operation sequences vary from calculator to calculator.
