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.
Transistor Fundamentals: AC Model Equations
By Patrick Hoppe
Students view the equations used to determine the ac parameters of the transistor circuit.
Noninverting Op Amp
By Terry Bartelt
In this animated object, learners examine the fundamental operation of a noninverting operational amplifier. A brief quiz completes the activity.
The Zener Diode: Practice Problems
Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.
Ultrasonic Sensors (Screencast)
In this animated activity, learners examine the operation of an ultrasonic sensor and the procedure to perform zero and span adjustments. A brief quiz completes the object.
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.
