The learner will be able to represent steady-state AC sinusoidal signals using phasors, which will lead to a simplified technique of analyzing AC circuits in a very similar way that we analyze DC circuits.

In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.

Learners will understand how the interaction of the armature magnetic field and the rotating stator field cause the rotor of a single-phase AC motor to turn.

In this animated activity, learners study how stator poles create a rotating field in a three-phase AC motor as a three-phase AC voltage is applied.
