Learners study an animated block diagram that describes the function of each element in a closed-loop system used in industrial automation.
Learners examine the factors that contribute to the delays in the response time throughout a closed-loop system.
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.
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.
In this lesson on atomic structure, learners examine how the binding energy of electrons affects light production in certain phosphors used in x-rays.
Learners examine how air-to-open valves and air-to-close valves are used in different situations. A brief quiz completes the activity.
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.
Students read how the transfer function is developed for an RC low-pass filter. A straight line Bode plot is drawn through close approximations.
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.
In this animated object, learners examine how an enclosed chambered metering system operates.
Learners take a close look at the information on product labels concerning fat, fiber, and serving sizes. A quiz follows the lesson.
In this animated and interactive object, learners examine a heat exchanger as an example of an automated closed-loop system.
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.
Students are introduced to the non-inverting amplifier configuration. The formulas for closed loop gain and bandwidth are shown, and an example is given.
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 read an explanation of the summing amplifier and the formulas for closed-loop gain. An example is given.
In this animated object, learners examine the operation of a feed-forward control system and its advantages over a closed-loop system. A brief quiz completes the activity.
In this interactive and animated object, learners examine open and closed head injuries and the common causes and symptoms related to them.
In this accounting learning object, students follow the steps involved in the closing process. Temporary accounts contain ending balances for a specified period and must be closed.
In this animated object, learners examine a closed-loop feedback system that uses digital circuits to control the position of a gear rack.
