Learners read an analogy comparing an electrical transformer to mechanical gears.
Transfer Functions: The RC High Pass Filter
By Patrick Hoppe
Learners read how the transfer function for a RC high 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.
Series-Parallel Circuit Analysis: Practice Problems Circuit 1
In this interactive object, learners analyze a series-parallel DC circuit problem in a series of steps. Immediate feedback is provided.
An Impedance Matching Application
By Terry Bartelt
Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
Electrical Units, Abbreviations, and Symbols
In this learning activity you'll read introduction to electrical quantities, units, and symbols and test their knowledge in a matching exercise.
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 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.
