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

Students view drawings of the emitter resistor bypass capacitor.

Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.

In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Learners study an animation of a spring-and diaphragm actuator controlling the opening of a flow valve.

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 causes of air leaks and read how to repair them. The object includes audio.

In this animated and interactive object, learners examine the basic parts and the linear movement of a hydraulic cylinder. A brief quiz completes the activity.

Learners examine the differences and similarities between hydraulic and pneumatic systems.
