Learners use the National Electrical Code to determine the size of a motor overload protection device.
Phase Relationships Between Line-Neutral and Line-Line Voltages
By Michael Gradinjan, Terry Fleischman
Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.
Voltage Waveforms in an Edison Three-Wire System
By Terry Bartelt
Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.
The Reynolds Number
In this animated learning object, users study the factors that affect a pipe’s fluid flow and how those factors pertain to a numerical value (the Reynolds Number).
Hall-Effect Sensor Application
Learners view practical examples of how a Hall-effect sensor is used.
Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.
The 12 Cranial Nerves
By Barbara Liang
In this interactive and animated object, learners read a description of the number, name, and function of the cranial nerves. A matching quiz completes the activity.
The Two-Neuron Knee-Jerk Reflex Arc
In this interactive object, learners examine the neuron pathway into and out of the spinal cord. They complete the activity by testing their knowledge of vocabulary and the location of spinal cord structures.
The Corticospinal Tracts
In this animated object, learners examine the major descending tracts of the nervous system. A matching exercise completes the activity.
The Upper and Lower Motor Neurons
In this animated object, learners examine the function and location of the motor neurons and the damage that can result when they are injured.
