Learners view two animations that show the effects of eddy currents.
Transfer Functions: The RL Low Pass Filter
By Patrick Hoppe
Learners read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.
By Terry Bartelt
In this animated activity, learners see that changing the resistance value of the load in the secondary of a transformer causes current to vary in the primary.
In this animated lesson, students view the operation of an electromechanical relay. A brief quiz concludes the activity.
In this animated object, students observe how the pulsating DC output voltage of a full-wave rectifier is filtered by a capacitor.
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.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
The Sine Wave
Using text and graphics, this learning activity describes a sine wave, including alternations, cycles, time, amplitude, and degrees
AC Current Flow
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.
