In this animated lesson, the learner examines how a ladder circuit causes the cylinder of a hydraulic circuit to make a single extension and retraction.
In this learning activity you'll explore the four stages of conflict (latent, triggering incident, conflict, new equilibrium) and then creates a similar diagram applying to a specific personal conflict.
Learners study the muscles of the scapula and check their knowledge on each page by identifying the muscles on diagrams and answering a related question about movement.
Learners examine the concept of propagation delay within a TTL logic gate. The concept is explained with the use of timing diagrams and sample calculations.
This interactive learning object is designed to help learners memorize the color code used on some hydraulic schematic diagrams. Learners quiz themselves using electronic flashcards.
In this animated object, learners examine the mechanical configuration of a three-way switch and how it operates in a circuit. They also view diagrams showing the use of an ohmmeter to determine the electrical connections.
In this screencast, learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.
Learners read an explanation of how to connect two 7485 ICs to compare binary numbers by creating an 8-bit comparator. Diagrams and charts are presented.
This interactive object is designed to help learners memorize schematic symbols used in hydraulic diagrams. Learners quiz themselves using electronic flashcards.
This interactive object is designed to help learners memorize schematic symbols used in pneumatic diagrams. Learners quiz themselves using electronic flashcards.
Nail Diseases and Disorders: A Case Study Assessment
Students view diagrams of nails and read the client's nail history. They then determine if the affected nail has a disease or a disorder and recommend salon treatment and home care.
In this module, we'll be introducing you to SIPOC, a powerful tool that can help you improve your business processes. It's a high-level process mapping tool that helps you identify the key components of a process and how they relate to each other. SIPOC diagrams are often used in Six Sigma and Lean methodologies, but they can be useful for any process improvement initiative. We’ll explain the key SIPOC components and demonstrate how to build one. Then, we’ll walk through a few scenarios and let you build your own.
Transistor Fundamentals: Collector Saturation and Collector-Emitter Cutoff
Students read about the concepts of saturation and cutoff. They view diagrams that illustrate the interaction of the load line and the family of curves.
In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.
In this animated object, students view diagrams of the UJT as it is used in the relaxation oscillator circuit. Waveforms illustrate how the circuit operates through several time periods.
