Learners follow a methodical approach for the dc analysis of series-parallel circuits.
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.
In this animated activity, learners examine how residual magnetism causes magnetic hysteresis.
Retro-Reflective Optical Sensors
Learners study the operation of the retro-reflective optical sensor, along with the guidelines that should be followed regarding the target size, reflector size, alignment, and the reflectivity of the target.
Analog Voltmeter Operation
Students follow the procedure to measure voltage with an analog voltmeter. They examine the use of the Function Switch and the Range Switch. A brief quiz completes the activity.
Reading and Interpreting Bar Graphs
By Francine Nettesheim
In this learning activity you'll identify the various parts of a bar graph, read and interpret its data, and calculate the data to solve various application problems.
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.
Cash Basis Accounting
By Julie Dilling
In this interactive object, learners read a brief summary of the principles of cash basis accounting and then check their knowledge of transactions in a drag-and-drop exercise.
Inductive Reactance Practice Problems
By Patrick Hoppe
Students solve problems on the determination of total inductive reactance of series-parallel inductors.
Capacitive Reactance Practice Problems
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
