This learning object is a really straight forward way of teaching the phase and line voltage relationships.
Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.
In this animated activity, learners see that changing the resistance value of the load in the secondary of a transformer causes current to vary in the primary.
Students view the development of the transfer function for a RC high pass filter. They also read how a Bode plot is developed through simple approximation techniques for both the magnitude and phase.
This game focuses on concepts relating to radio frequency modulation.
