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 animated object, learners view a race of two boats as an example of how the derivative function of a PID controller shortens the time duration of an operation.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

Learners observe the animated operation of an astable mulivibrator using a 555 IC (integrated circuit) chip and external components.

In this animated object, students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.

Students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.

In this animated and interactive object, learners examine the formula for horsepower and work practice problems.

In this animated activity, learners examine the circuitry in a DC variable speed drive that causes the motor to accelerate or decelerate at slow rates. This learning object has audio content.

In this animated lesson, learners examine the rectifier circuitry in a DC variable speed drive that supplies the voltages to the field coil and armature.
