In this animated object, learners examine the operation of a closed-loop system that maintains the speed of a conveyer belt as heavy boxes are placed or removed.
Normally Open vs. Normally Closed Pressure Control Valves
In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.
The inverting amplifier configuration is presented. The closed loop voltage gain and the closed loop bandwidth formulas are explained, along with the concept of negative feedback.
Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.
Students read an explanation of the use of questionnaires in research. Open-ended and closed-ended questions are defined. Students complete the activity by generating a questionnaire.
Students are introduced to the non-inverting amplifier configuration. The formulas for closed loop gain and bandwidth are shown, and an example is given.
Learners view an animated presentation showing how the pH level of a cleaning solution is controlled in a closed-loop system in a manufacturing setting. A quiz completes the activity.
Learners study animations showing the integral function of a closed-loop control system and the difference between the two types of integral controller settings, reset rate and reset time. A short quiz completes the activity.
In this scenario, learners take the role of a delivery driver who must find a new travel route after the Interstate is closed to trucks. “Drivers” listen to traffic reports and write directions for a new route. This activity has audio content.
