In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

In this learning activity you'll solve three binary subtraction problems using the 2's complement method.

Learners study how a hydrocarbon gas sensor operates and why it is used. A short quiz completes the activity.

Learners read how to use the arctangent function to calculate the theta of an angle. The proper keystrokes are displayed.

In this animated activity, learners read about air loss in a pneumatic system and ways to reduce the leakage. The object includes audio.

In this animated object, learners examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.

Learners use animated needle valves and check valves to change the speed of a pneumatic cylinder as it extends and retracts. A brief quiz completes the learning object.

This animated lesson shows how pushing a start or stop button on a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.

This animated lesson an exercise that enables students to design a ladder logic circuit using a drag-drop function to cause the cylinder of a hydraulic circuit to extend and retract.
