The learner views a method to find the total complex power of a circuit in which the individual real and reactive powers are found and then added together. Several examples are shown, along with the power triangles.

Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.

Students read an explanation of power factor in a power distribution and how it can be improved by using a power factor correction capacitor bank. A brief quiz completes the activity.

In this learning activity you'll explore the four stages of conflict (latent, triggering incident, conflict, new equilibrium) and then creates a similar diagram applying to a specific personal conflict.

Learners examine how CEC, base saturation, and soil pH work with each other to define plant nutrient availability.

Learners identify negative roles, match statements characteristic of each role, and relate how they have handled negative teams.

In this learning activity you'll discover how the Eagle Power Roller control panel operates.

Students read about the concept of true power and view examples of how it is dissipated as heat is provided.

Learners read an explanation of the concept of apparent power in a power distribution system involving motors, generators, and transformers. A quiz completes this interactive lesson.

In this animated object, learners examine the parts of a pneumatic power system, including the prime mover, compressor, and receiver tank, and how they function.

Students read an explanation of reactive power in a power distribution system involving motors, generators and transformers. A brief quiz completes the activity.

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

The student studies the method to calculate complex power where the Vrms of a circuit is multiplied by the complex conjugate of the total circuit current. Several examples are given, along with the power triangle.

Use Ohm's law, Watt's law, and the power equation to derive formulas for the DC power wheel.

Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.

Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

In this animated object, learners examine what anxiety is, how it affects people, and ways to manage it.

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.

Learners are introduced to the maximum power transfer theorem. Examples show the load as it varies and the results are graphed.

Students read an explanation of power factor correction. Examples of both inductive and capacitive loads are given.
