In this learning activity you'll explore how a fuse de-energizes a parallel circuit when too many lamps are connected to a power outlet.

In this simulation activity, the lubrication fluid in a milling machine is tested, the condition of its 24 drill bits are inspected and identified before replacing those that are defective.

In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object.

In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.

Learners examine the speed control circuits in a DC variable speed drive that cause the RPM of a motor to vary. This activity has audio content.

In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.

Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.
