In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.
The learner studies how electrons travel from one atom to the next. Examples demonstrate how voltage is created by the use of a battery or through magnetism. A quiz completes the activity.
In this interactive object, learners review descriptions of various blood collection tube additives. They then test their knowledge by matching the different tubes to their corresponding additives.
In this animated activity, learners examine the conversion of electrical energy into an electrostatic charge within the dielectric material of a capacitor.
Ions are electrically charged particles obtained from an atom or from a chemically bonded group of atoms by adding or removing electrons. Eight examples illustrate the number of protons, neutrons, and electrons in positive ions (cations) and in negative ions (anions).
In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.
In this learning activity you'll analyze an introduction and determine whether or not it was effective. You'll also gain an understanding of what makes an effective introduction.
Using a memory shortcut for calculations, the learner determines line and phase values of current in a three-phase AC configuration. Practice problems complete the activity.
