Good visual for lecture
This made the AC sine Wave much more clear and I will use this for my welding students.
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.
In this interactive object, learners examine how voltages and currents vary in a parallel LC circuit as the applied frequency changes.
You'll learn some concepts related to radio frequency modulation.
You'll learn to identify frequency bands of the electromagnetic spectrum licensed by the FCC.
