In this screencast, learners examine the interaction between a conductor that represents a motor armature and a magnetic field that represents a motor’s main field. This interaction causes the shaft to turn.

Learners examine the process for determining the total inductance of a parallel circuit. They then complete practice problems.

In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.

Learners study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.

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.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

Students work six practice problems to determine the total impedance of a parallel circuit.
