Using text and graphics, this learning activity describes a sine wave, including alternations, cycles, time, amplitude, and degrees
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.
This learning object describes the production of an alternating current in a generator with a single-loop armature. An illustration of how a sine wave is produced is shown through animation.
You'll focus on how radio frequencies spread under different circumstances.
You'll learn some concepts related to radio frequency modulation.
You'll learn to identify antenna terms and concepts.
