This learning object is a really straight forward way of teaching the phase and line voltage relationships.
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
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.
You'll learn some concepts related to radio frequency modulation.
