The learner will examine how torque is developed in an induction motor.

In this interactive and animated object, learners examine how dc voltages develop across capacitors that are connected in series and in parallel.

In this interactive object, learners calculate a centroid of a composite area by first creating a chart. A short quiz completes the activity.

In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.

In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.

In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

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.

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.

You'll learn some concepts related to radio frequency modulation.
