Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
Series Circuit Analysis Practice Problems: Circuit #6
By Patrick Hoppe
In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.
Identifying Lever Classes
By James Bourassa
In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
This learning object introduces the three approximations of a diode.
Sinking/Sourcing Output Module
By Terry Bartelt
Learners examine the sourcing and sinking of conventional current at a PLC output module and the type of field device to which it is connected. This interactive learning object includes six quiz questions.
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.
