Students read how to determine the total impedance of a parallel circuit using complex numbers. The "J" term is used in the calculations.

In this animated activity, learners study how stator poles create a rotating field in a three-phase AC motor as a three-phase AC voltage is applied.

Learners read an explanation of how the Magnetron Ignition System uses a solid state switching component, a step-up transformer, and magnetism to provide a high voltage spark in a one-cylinder combustion engine.

In this video you'll study the structure of the cell membrane and construct it using the correct molecules.

Learners develop 3D visualization skills by examining front, side, and top orthographic views of objects. Using this information, students select the corresponding isometric view of each object.

The user completes a fill-in-the-blank exercise to review the anatomy of the heart.

In this interactive learning object, students view the ammeter connections for measuring currents in a parallel circuit with three branches on an energy concepts lab board. A brief quiz completes the activity.

Learners read how the RL high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

In this animated activity, learners examine the difference between opens and shorts in an electrical circuit. A brief quiz completes the object.

The learner will be able to represent steady-state AC sinusoidal signals using phasors, which will lead to a simplified technique of analyzing AC circuits in a very similar way that we analyze DC circuits.

Students identify the various regions of the human body through video.

In this interactive object, learners identify a variety of prevention activities as primary, secondary, or tertiary.

In this animated object, the learner examines 17 types of joint movement.

In this learning activity you'll be introduced to the cause and effect diagram.

In this screencast you'll identify and write assertive "I" statements that focus on BCF (behavior, consequences, and feelings).

In this learning activity you'll practice converting between hexadecimal and decimal and between hexadecimal and binary numbers.

In this learning activity you'll review how a short affects current flow and voltage in a series circuit.

In this interactive object, students view an animated depiction of Class 1 levers. A matching quiz completes the activity.

In this interactive object, the learner matches various disorders to the acid-base disturbances they cause.

In this animated object, learners examine how psychotropic medications act on neurotransmitter systems to achieve their desired effect.

In this animated activity, learners read about the types of lines found on blueprints. A quiz completes the activity.

Learners will test their ability to read a depth micrometer in this interactive quiz.

Learners examine how to multiply the gate propagation delay by the gate power dissipation to find the speed-power product. Examples are shown.

After a brief review, the student solves five practical shop problems using right angle trigonometry.

In this screencast, learners review the parts of the gastrointestinal system and then check their knowledge in a matching exercise.
