In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
Power Law Practice Problems #4
By Patrick Hoppe
Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.
Torque Sequence of Two Mating Surfaces
By James Bourassa
In this interactive object, learners demonstrate the proper tightening sequence for mechanically joining two mating surfaces.
Waste in the Office
By Kaye Krueger
Learners view examples of waste in an office environment and are asked to consider what they can do to eliminate or reduce waste in their own workplace.
Summing Op Amp
By Terry Bartelt
In this animated object, learners examine the operation of a summing operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.
AC Current Flow
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
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 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.
Students read an explanation of reactive power in a power distribution system involving motors, generators and transformers. A brief quiz completes the activity.
