In this animated and interactive object, learners follow steps to perform the process identification procedure for the Ziegler-Nichols Continuous Cycling Tuning Method. 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 use the Pythagorean Theorem to calculate forces.

In this animated activity, learners examine the conductivity of a solution and how its properties affect measurements to determine concentration levels. A brief quiz completes the learning object.

In this animated and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.

In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. They then answer six multiple-choice questions.

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.

Learners examine the speed control circuits in a DC variable speed drive that cause the RPM of a motor to vary. This activity has audio content.

Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.
