Students answer five questions concerning magnetism.
Pneumatic Directional Control Valves (Screencast)
By Terry Bartelt
In this animated object, learners examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.
Development of a Boolean Expression for a Combinational Logic Circuit
By Patrick Hoppe
Learners view an animated demonstration of how to determine the final output of the combinational circuit.
The Time-of-Flight Flowmeter
Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.
Oscilloscope AC Voltage Measurements
In this animated learning object, students view the operation of an oscilloscope that is used to measure AC voltages. 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.
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.
