In this high school lab, students design and build one of the basic circuits of electrical engineering: the voltage divider -- a form of linear circuit capable of producing a wide range of output voltages. The lesson provides scaffolding as students explore the mathematical relationships of parallel and series resistors as they build light emitting diodes. The driving question of the lesson: How do electrical engineers apply Ohm's law in the design of electrical circuits?
The lesson follows a module format that includes objectives and learner outcomes, problem sets, student guides, recommended reading, illustrated procedures, worksheets, and background information about the engineering connections. The lesson plan and student worksheets are available for download. This collection maintained by the Institute of Electrical and Electronics Engineers. Editor's Note: This lesson is a stand-out because of the comprehensive supplemental material, including step-by-step breadboard instructions and matrices of possible voltage outputs. For additional student practice, see Related Materials to download an editor-recommended worksheet on voltage divider electronics (37 problems with answers provided).
