Students view drawings of the emitter resistor bypass capacitor.
Using the Microstepping Technique for Stepper Motors
By Terry Bartelt
Learners view animations showing how electrical signals are applied to the coils of a stepper motor to perform microstepping. A short quiz completes the activity.
Optical Encoder Classifications
In this animated object, learners examine the two types of optical encoders used in automation applications: incremental and absolute. A brief quiz completes the activity.
Resistor Color Code Description
By Patrick Hoppe
In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.
Who Wants to Be an "Engin-aire?" -- Nonferrous Metals and Alloys
By Bryan LaVigne
Learners answer questions about nonferrous metals and alloys using a game show format. Immediate feedback is provided.
Parallel RC Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
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.
In this interactive object, learners examine the physical facets that determine the value of a capacitor. A brief quiz completes the activity.
This learning activity presents information on how the type of material used for the dielectric of a capacitor affects the capacitor's value in farads.
