Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
By Terry Bartelt, Stephen Schneider
In this colorful and animated activity, learners examine the four functions provided by a hydraulic reservoir. A brief quiz completes the learning object.
Op Amp Fundamentals: The Transresistance Amplifier
By Patrick Hoppe
The current-to-voltage conversion of the transresistance amplifier is examined. The formulas for output voltage and impedance are defined and an example ties the concepts together.
Phase Relationships Between Line-Neutral and Line-Line Voltages
By Michael Gradinjan, Terry Fleischman
Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.
PLC Sourcing Input Modules
By Terry Bartelt
In this interactive and animated object, learners study how to wire field devices to a PLC sourcing input module. A brief quiz completes the activity.
Accrual Basis Accounting
By Julie Dilling
Learners reinforce the matching concept in accrual basis accounting through a drag-and-drop exercise.
