In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
Calibrating an Opposed Optical Sensor
By Terry Bartelt
In this animated and interactive object, learners follow three steps to calibrate an opposed optical sensor. They consider horizontal alignment, the sensitivity setting, and having an effective beam.
In this animated object, learners read about hydrostatic pressure and observe how it is used to measure the level of a material in a container.
Ammeter Circuit Connections
In this animated activity, students view a step-by-step approach of how to connect an ammeter to a circuit. A brief quiz concludes the lesson.
Series RC Circuit Practice Problems
By James Bourassa, John Rosz
In this interactive object, students calculate capacitive reactance, phase angle, impedance, and power in series RC circuits.
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.
