Learners view the operation of a full-wave rectifier which has two diodes.
By Terry Bartelt, Terry Fleischman
In this animated object, learners study how the internal parts of an AC synchronous motor interact with magnetic fields to cause rotation. A short quiz completes the activity.
The Induction Motor Slip
In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.
Logic State Indicators
By Terry Bartelt
Instructions on how to interpret state indicator symbols for input and output terminals of digital devices is presented.
Op Amps 6: Circuit Resistance for the Inverting Amplifier
By Todd Van De Hey
The learner will calculate input and output circuit resistance for the Inverting Op-Amp configuration.
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.
The Sine Wave
Using text and graphics, this learning activity describes a sine wave, including alternations, cycles, time, amplitude, and degrees
The Generation of Alternating Current
This learning object describes the production of an alternating current in a generator with a single-loop armature. An illustration of how a sine wave is produced is shown through animation.
Mathematical Expression of an AC Sine Wave
By Patrick Hoppe
Students view the mathematical expression of an AC waveform with respect to time (t) and read about the different components of this expression.
