Learners study the muscles of the scapula and check their knowledge on each page by identifying the muscles on diagrams and answering a related question about movement.
Rotating Vector Representation of the Sine Function
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.
How Adding Parallel Branches Increases Total Current
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.
