Good visual for lecture
This made the AC sine Wave much more clear and I will use this for my welding students.
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 examine how voltages and currents vary in a series RLC circuit as the applied frequency changes.
Students view the mathematical expression of an AC waveform with respect to time (t) and read about the different components of this expression.
Identify frequency bands of the electromagnetic spectrum, licensed by the FCC.
This game focuses on concepts relating to radio frequency modulation.
