Unit 3: Switches, Bridge Circuits, and Sensors

Unit Description:

This teaching unit from Louisiana Delta Community College is part of a high school basic electronics course from Project COMPLETE (Controlling, Operating, and Measuring: Pathways for Learners to Engineering Technology Employment). The course is intended for use in a project-based learning environment. Unit 3 provides information on switches, bridge circuits, and sensors. Topics covered include: maintained switches, momentary switches, bridge circuits, photoresistors, and more. The other six units from the course cover additional topics related to electronics and are available to view separately.

Unit Contents: 

This unit includes eight PowerPoint presentations, four sets of section review questions, two tests and a test key, an activity, and a graphic organizer. 

The presentations are each dedicated to an individual topic for the unit and are labeled according to the order in which they are to be presented. The section review questions are intended to be given after each set of presentations. Answers to the section review questions are included.  The tests and test key cover the assessment questions and answers for this unit. The activity provides a control panel simulation activity. The graphic organizer provides unit concepts and definitions; as well as terms, notation, formulas, and diagrams. 

For orientation purposes 07a_BridgeCircuit.pdf is included as a separate attachment and offers a sample of the type of material included in this unit. 

Below is a list of the files included in the .zip attachment. The size of each file is included in parenthesis.
