In this interactive object, learners answer nine questions about series and parallel circuits. Immediate feedback is provided.

Students read about the operation of the zener diode. This activity includes the ideal zener, the breakdown operation, the calculation of series, and zener and load current.

Learners examine an animation that shows how an AC voltage is produced as an armature rotates within a magnetic field. Ten review questions complete the learning object.

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 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.

In this animated object, learners examine the operation of a pneumatic directional control valve using air pilot lines.

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.
