Students read an explanation of the Voltage Divider Rule with complex numbers. Examples are given.
Pneumatic Cylinder Flow Control
By Terry Bartelt
Learners use animated needle valves and check valves to change the speed of a pneumatic cylinder as it extends and retracts. A brief quiz completes the learning object.
In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. They then answer six multiple-choice questions.
Excel: Converting Radians to Degrees
By Patrick Hoppe
Students read how to use the DEGREES() function to convert radians to degrees.
The Three-Phase AC Generator
By Terry Fleischman
In this 3D animated object, learners examine the way in which a three-phase generator produces three sine waves with three armature coils. A quiz completes the activity.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
