In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
Selecting a Proper Single Phase Transformer
By Gary Lindell, Terry Bartelt
Students follow the steps that are required to select a transformer with the proper ratings. Voltage, frequency, current, and KVA are considered.
Transistor Fundamentals: AC Coupling Capacitors
By Patrick Hoppe
Students view the design and function of an ac model for a transistor circuit.
Statics -- Trig: The Law of Sines
By Steve Whitmoyer
In this interactive object, students use the Law of Sines to calculate forces.
Voltages Across Series and Parallel Capacitive Circuits
By Terry Bartelt
In this interactive and animated object, learners examine how dc voltages develop across capacitors that are connected in series and in parallel.
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.
