Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
Kirchhoff's Current Law
By Tim Tewalt, Patrick Hoppe
Learners observe how branch current values in parallel circuits are affected when different values are used. They test their knowledge by answering 11 review questions.
Reversing the Rotation of DC Motors
By Terry Bartelt, Terry Fleischman
Learners view animations showing how to change the connections to cause a DC motor to reverse its rotation. A short quiz completes the activity.
By Terry Bartelt, Pat Jensen
In this learning activity, we’ll explore the impact of electric shock on the human body.
Parallel Circuit Analysis Practice Problems: Circuit #5
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 by each resistor.
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
By Terry Bartelt
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.
