Learners view the operation of a full-wave rectifier which has two diodes.
By Terry Bartelt
In this animated lesson, students view the operation of an electromechanical relay. A brief quiz concludes the activity.
The TI-86 Calculator: The Complex Conjugate
By Patrick Hoppe
Learners view the steps to find the complex conjugate of a number in polar form using a TI-86 calculator.
Transistor Fundamentals: The MOSFET
Students read an introduction to the Metal Oxide Semiconductor Field Effect Transistor. They also examine its enhancement mode.
In this animated object, learners examine the operation of a demultiplexer along with the data output and select lines. A brief 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.
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
Students view the mathematical expression of an AC waveform with respect to time (t) and read about the different components of this expression.
