Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
The TI-83 Plus Calculator: The Mode Function (Setting Up Your Calculator)
By Patrick Hoppe
The learner examines the setup process of a TI-83 Plus calculator. The process is demonstrated and examples are given.
Labeling DC Motor Connections
By Terry Bartelt
Learners examine the connections of a DC motor and how the terminals are labeled. A matching exercise completes the learning object.
In this animated object, learners examine the signals produced by sourcing and sinking two-wire sensors. A brief quiz completes the activity.
Graphical BJT/JFET Transistor Biasing
By Roger Brown
Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.
Accrual Basis Accounting
By Julie Dilling
Learners reinforce the matching concept in accrual basis accounting through a drag-and-drop exercise.
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.
Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.
