In this animated activity, learners examine how ground fault circuit interrupters work and why they are an important safety feature.

This animated lesson shows how a pressure switch connected in a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.

In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.

In this interactive object, learners view a practical application of a PLC Timer-On function.

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.

This game is a great practice for anyone who needs help knowing information about Branches of Government, Constitution and Supreme Court.
