Learners answer six questions about transformers.
Repetitive Cylinder Cycling
By Terry Bartelt
In this animated activity, learners examine the operation of a pneumatic cylinder that continuously cycles by extending and retracting.
GD&T - The Feature Control Frame
By Glenn Sokolowski
In this interactive object, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information. A brief quiz completes the activity.
Analog Voltmeter Operation
Students follow the procedure to measure voltage with an analog voltmeter. They examine the use of the Function Switch and the Range Switch. A brief quiz completes the activity.
The Universal NAND Gate
In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.
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.
