Learners study how a circuit converts the AC output of a linear voltage differential transformer (LVDT) into variable DC voltage. It is recommended that learners view the learning object IAU7807, “The LVDT: A Linear Voltage Differential Transformer in Action” before going through this 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 learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
In this learning activity you'll read descriptions of military standards, ANSI, ISO, calibration system standards and audit system reference standards. These topics would be important for the CQT (certified quality technician).
In this learning activity you'll read about the 12 million refugees in the world, from what countries they come, and what countries give them refuge. Learners locate some of these countries on maps in an interactive exercise.
In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.
Users of this learning object review a case study of an online student and her experience with her instructor. They determine the principles of good practice for teaching online.
In this interactive learning object, the student matches the names of software with their definitions and categorizes computer terms according to the appropriate software.
In this learning activity you'll review the operation of an Exclusive-NOR gate by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.
