In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.
In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.
In this animated and interactive object, learners examine the inverse proportionality of wavelength and frequency and their relationship to the speed of light.
Students view photos of an electric pencil sharpener as it is disassembled. The learning object is intended to prepare students to be able to identify the components and create an assembly process in a future activity.
