This course covers a basic introduction to circuit components and their applications in DC and AC circuits. It also provides an introductory look at the operational amplifier device and basic operation of two-input logic gates and their circuits. This is the third segment of introductory physics that revises and expands on selected areas of high school physics and prepares the engineering student for more advanced topics in physics and engineering.  Selected assignments and laboratory exercises are included and are designed to reinforce and expand the student understanding of the fundamental concepts and their application to solving engineering problems.
