Learners view two animations that show the effects of eddy currents.
AC Current Flow
By Terry Bartelt
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 object, learners examine the fundamental operation of a diac including how it is turned on and turned off. A brief quiz completes the activity.
Statics: Scalar vs. Vector
By Steve Whitmoyer
Learners read an introduction of scalar quantity and vector quantity and force. Examples are given.
Determining Hydraulic Cylinder Size
Students read how to calculate the size of a hydraulic cylinder that is required for a particular application. Mathematical formulas are provided.
Financial Statement Analysis
By Lynette Teal
Learners read the definitions of working capital, current ratio, quick ratio, return on equity, accounts receivable turnover, and inventory turnover.
Transformer Action Demonstration
Learners view animations and video clips showing how power is transmitted from one energized coil to another.
Inductive Reactance Demonstration 1
Learners view video clips showing how coiled wire provides more resistance to AC current flow than uncoiled wire.
Instantaneous Current Calculations of a De-Energizing RL Circuit (Using a TI-30XIIS Calculator)
Students view a sample of the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous current of a de-energizing circuit.
Instantaneous Current Calculations of a De-Energizing RL Circuit (Using a TI-36X Calculator)
Students view a sample of the keystrokes used on a TI-36X calculator to solve for the instantaneous current of a de-energizing circuit.
