Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.
Total Impedance of a Series Circuit Using Complex Numbers
By Patrick Hoppe
Students view several examples of how to determine the total impedance of a series circuit. The "j" term is used in all of the calculations.
Parallel Inductance: Practice Problems
Students work nine practice problems to determine the total inductance of a parallel circuit. Immediate feedback is given.
The Kelvin Temperature Scale
By Terry Bartelt, Pravina Shah
In this animated object, learners examine why and when the Kelvin scale is used. A brief quiz completes the activity.
Voltages Across Series and Parallel Capacitive Circuits
By Terry Bartelt
In this interactive and animated object, learners examine how dc voltages develop across capacitors that are connected in series and in parallel.
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.
An Inductor Opposing a Current Change
Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.
The Magnetic Circuit
Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.
Interpreting Engineering Drawings: Common Abbreviations
By Glenn Sokolowski
In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.
Interpreting Engineering Drawings: Title and Revision Blocks
Learners examine the information on a title block and answer questions about that information in an interactive quiz.
