Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
In this interactive object, students complete progressively more difficult exercises as a way to improve their ability to recognize resistor color code values.
Learners use animated needle valves and check valves to change the speed of a pneumatic cylinder as it extends and retracts. A brief quiz completes the learning object.
Identify the forms of energy through definition and example.

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.
Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.
In this animated activity, learners see that changing the resistance value of the load in the secondary of a transformer causes current to vary in the primary.
You'll be introduced to commonly used acronyms within the computer industry.
