In this interactive object, learners read a description of value-added and non-value-added activities and then place various work duties into these two categories.

Learners view the steps for determining the square root of a complex number in Excel.

Learners view animations showing how electrical signals are applied to the coils of a stepper motor to perform microstepping. A short quiz completes the activity.

In this screencast, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts.

Students solve problems on the determination of total inductive reactance of series-parallel inductors.

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.

Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.

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

You'll practice defining terms relating to cylinders and identifying parts of cylinders.

You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
