Students read the multivariable theorems and view the graphic depictions of the Boolean expressions.

Learners read about the vector diagram for a parallel RL circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.

In this animated learning object, users study the factors that affect a pipe’s fluid flow and how those factors pertain to a numerical value (the Reynolds Number).

Learners view steps to reduce changeover time in a manufacturing operation.

Learners reinforce the matching concept in accrual basis accounting through a drag-and-drop exercise.

Learners consider why an impedance matching transformer is needed to connect an antenna to a television.

Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.

Learners view animations and video clips showing how power is transmitted from one energized coil to another.

Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.
