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.
Light-Emitting Diodes (LED)
By Patrick Hoppe
Students read about light-emitting diodes, including LED voltage and current, and how to protect against reverse voltage.
By Terry Bartelt
In this learning activity you'll determine the voltages that can be topped off of a multi-resistor voltage divider that has one main power source.
Summing Op Amp
In this animated object, learners examine the operation of a summing operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.
Converting Numbers from Standard Form to Engineering Notation
By Ron Wallberg
Learners convert a number from standard form to engineering notation.
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.
By Terry Fleischman
In this learning activity you'll read the procedures for using the vertical function of an oscilloscope and view illustrations of waveforms.
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
The Op Amp Non-Inverting Amplifier Configuration
You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
