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.
By Terry Bartelt
Learners observe how an optical pyrometer is used to take temperature measurements without making physical contact with the object being measured.
Hall-Effect Sensor Application
Learners view practical examples of how a Hall-effect sensor is used.
The TI-86 Calculator: The Square Root Function
By Patrick Hoppe
Students read step-by-step instructions for determining the square root of a number using the TI-86 calculator.
Parallel Circuit Analysis Practice Problems: Circuit #8
In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.
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.
AC Voltage Conversion Problems
By John Rosz, Terry Bartelt
Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
AC Voltage Conversions
In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.
AC Current Flow
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
