Learners will understand how the interaction of the armature magnetic field and the rotating stator field cause the rotor of a single-phase AC motor to turn.
The Torque of an Induction Motor
By Terry Fleischman
The learner will examine how torque is developed in an induction motor.
Voltages Across Series and Parallel Capacitive Circuits (Screencast)
By Terry Bartelt
In this interactive and animated object, learners examine how dc voltages develop across capacitors that are connected in series and in parallel.
Strength of Materials: Centroids of Composite Areas
By Steve Whitmoyer
In this interactive object, learners calculate a centroid of a composite area by first creating a chart. A short quiz completes the activity.
Displacement and Velocity Ratios
By James Bourassa, John Rosz
In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.
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.
