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.
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.
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 object, learners drag resistors of the proper value into a series circuit to cause a required amount of current to flow. Seven review questions complete the activity.
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 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.
Learners study animated rheostat settings that show how varying the current flow affects the amount of power that is dissipated in a series circuit. Nine review questions complete the activity.
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.
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.
