Learners read an analogy comparing an electrical transformer to mechanical gears.
Highway Design: Vehicle Types
By Steve Whitmoyer
In this animated object, learners read the dimensions of the different types of vehicles typically considered in highway design.
Pneumatic Power Supply
By Terry Bartelt
In this animated object, learners examine the parts of a pneumatic power system, including the prime mover, compressor, and receiver tank, and how they function.
BCD-to-Seven Segment Decoder
By Terry Bartelt, Terry Fleischman
Learners will understand how binary-coded decimal information is decoded and used to drive a seven-segment display.
By Patrick Hoppe
The student studies the method to calculate complex power where the Vrms of a circuit is multiplied by the complex conjugate of the total circuit current. Several examples are given, along with the power triangle.
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 Impedance Matching Application
Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
The Reflected Load in a Transformer
Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.
Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity.
Transformer Action Demonstration
Learners view animations and video clips showing how power is transmitted from one energized coil to another.
