The Basic Electronics Course is intended for those teachers and instructors that want a ready resource that they can adapt to their instruction of electronic fundamentals. The materials include a PowerPoint presentation and instructor's script. The course is designed around affordable components, prototyping board, and VOM. The topics discussed during the course include:
The topics up to and including Ohm's Law are considered the most basic and are covered in detail. The remaining topics cover additional fundamental components of basic electronics however they receive only brief coverage.
The course can be presented in platform discussion, guided practice, and open question format as the material dictates. The course uses a standardized volt-ohm-meter (VOM) to help with the logistics of classroom management.
The course begins with a discussion of the three components that make up electricity. Then extensive time is spent on how to measure the three components of electricity. During this section two of the three components (voltage and current) are explored. This section covers VOM basics and to allow the student to become familiar with the most important and most basic piece of test equipment. The next section on circuit diagrams presents how electronic components are symbolized on an electronic road map called a schematic or circuit diagram. The intention here is to develop the fundamentals of interpreting circuit diagrams so that these illustrations of the arrangement of electronic components can be used to help with the remainder of the course. The final of the three components, the resistor, is covered next. How the three components are related mathematically, Ohm's Law, is covered in detail. The sections up to this point make up the basic concepts of electronics.
Four additional components common to virtually all electronic circuits are the capacitor, inductor, diode, and transistor. These topics are covered with a level of detail that familiarizes the student with the function of these components and the basics of how they work and react in difference situations.
The recommended reference for this course is Understanding Basic Electronics, sold separately.
