In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
In this animated and interactive object, learners examine kinetic and potential energy as well as the first law of thermodynamics and the flow of energy between a system and its surroundings. Students also answer questions about exothermic and endothermic reactions
How Adding Parallel Branches Decreases Total Resistance
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.
How Adding Parallel Branches Increases Total Current
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.
Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.
Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.
In this colorful and animated activity, learners study the operation of a needle valve and the operation of the needle valve with a check valve. A brief quiz completes the activity.
Financial Statements: What Are They? What Do They Mean?
Learners read about the most common forms of financial statements including balance sheets, cash flow statements, and profit and loss statements. A brief quiz completes the activity.
Learners study the most common ways to measure fluid flow for industrial processes including absolute quantity, percentage, volumetric flow rate, and mass flow. A brief quiz completes the activity.
