In this interactive object, students view an animated depiction of Class 2 levers. A matching quiz completes the activity.
Complex Power: The Sum of the Individual Real and Reactive Powers
By Patrick Hoppe
The learner views a method to find the total complex power of a circuit in which the individual real and reactive powers are found and then added together. Several examples are shown, along with the power triangles.
Inductor Series - Parallel: Practice Problems
Students complete 10 practice problems.
Capacitors: What's Inside?
Learners examine the properties that determine capacitance.
Sensor Wiring Configurations
By Terry Bartelt
In this animated object, learners examine how two- three- and four-wire sourcing and sinking sensors operate. A brief quiz completes the activity.
How Pressure Changes Boiling Temperature
By Terry Bartelt, Terry Fleischman
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.
Identifying Lever Classes
By James Bourassa
In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
