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.
Learners use this Structured Query Language tutorial to gain an understanding of how a SELECT statement is built. This learning object has audio content.
Explore how to prevent injuries caused by falling from ladders or elevated heights by looking at the parts of a ladder, ladder safety rules, and personal fall protection systems.
In this animated activity, students view the plastic pellets in a profile extrusion machine being melted as the temperature of the heating elements is elevated by a time proportioning control system.
Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.
The Time Proportioning Operational Amplifier (Screencast)
In this animated object, learners see how a time proportioning operational amplifier varies an average DC voltage. A brief quiz completes the activity.
