This learning object is a really straight forward way of teaching the phase and line voltage relationships.
Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
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.
This game focuses on concepts relating to radio frequency modulation.
