Rotating Vector Representation of the Sine Function
The learner will be able to represent steady-state AC sinusoidal signals using phase vectors, which will lead to a simplified technique of analyzing AC circuits in a very similar way that we analyze DC circuits.
In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.
In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.
