The effect of connecting voltage sources in parallel to increase amperage to a load is presented.

Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.

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.

Learners consider the factors that determine how well an inductive proximity sensor can detect an object. Those factors are size, position, and the material from which the target is made. A brief quiz completes the activity.

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.
