Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
Development of a Boolean Expression for a Combinational Logic Circuit
By Patrick Hoppe
Learners view an animated demonstration of how to determine the final output of the combinational circuit.
ElectroMagnetic Radio Waves
By Terry Bartelt
In this animated object, learners examine how magnetic waves are transmitted as radio signals.
By James Bourassa, John Rosz
Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.
In this learning activity you'll explore the operation of a NAND gate using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.
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.
