In this learning activity you'll explore the functions and proper operation of a digital multimeter.
By Terry Bartelt, Stephen Schneider
Learners view an animation of a counterbalance valve in operation and examine the valve’s internal structure.
Transistor AC Analysis Practice Problem: Circuit #4
By Patrick Hoppe
The learner solves for Zin(base), Zin(stage), Zout, and Av. A "help" screen is available.
Fundamentals of a DC Motor
By Terry Bartelt, Terry Fleischman
Learners study the interaction between the conductors of the stator and the armature inside a DC motor, which causes the shaft to rotate. A short quiz completes the activity.
Impedance: Series to Parallel Conversion
Students view the formulas to be used to convert a series impedance to a parallel impedance.
The Vertical Portion of the Sine Wave
By Terry Bartelt
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.
