In this interactive object, learners calculate a centroid of a composite area by first creating a chart. A short quiz completes the activity.

Students view drawings of the emitter resistor bypass capacitor.

Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.

Learners examine the internal parts of a DC electrical motor and then text their knowledge in a drag-and-drop exercise.

Learners view videos of law enforcement and corrections officers describing their jobs and the opportunities in their fields. Because this object contains large video files, it is best viewed using a high band width connection. Low band widths will result in longer download time and video delays.

Students answer five questions concerning magnetism.

Learners solve for voltage, current, and power in a single source, six-resistor circuit. A help screen is provided.

Learners solve 14 problems related to voltage, current and power in a single source, six-resistor circuit. A help screen is provided.

Learners examine a series-parallel circuit and solve 14 problems related to voltage, current and power. A help screen is provided.
