AC Voltage Conversion Problems
By John Rosz, Terry Bartelt
Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
Reaction Curve Tuning Example
Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.
Fundamentals of a DC Motor
Learners study the interaction between the conductors of the stator and the armature inside a DC motor, which causes the shaft to rotate. A short quiz completes the activity.
Methods of Producing Electricity
In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
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.
