In this animated object, learners examine how a coil of wire provides more resistance to AC current flow than an uncoiled wire. This learning object contains audio.
Learners examine the conventional current flow at a PLC input module, along with the field devices connected to it. This interactive object includes quiz questions and feedback.
Students read about the Federal Reserve System's structure and goals and the tools it uses to control the flow of money and credit in the economy. At the end of this activity, learners are asked to write how they would solve specific economic problems if they served on the Fed's Board of Governors.
In this animated, audio and graphic activity illustration, learners will view design criteria for properly storing property and evidence.
Learners will be able to identify areas within the property room including adjoining work areas, work flow, temporary storage, long-term storage, high profile items, bulk or oversize items, biohazards, hazardous materials, cold storage, administrative area, and release areas.
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
Learners examine the main characteristics of the four financial statements required in accounting: the income statement, the owner's equity statement, the balance sheet, and the statement of cash flow.
Learners read about the vector diagram for a parallel RL circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.
In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.
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.
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.
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.
