Students read about the concept of true power and view examples of how it is dissipated as heat is provided.
Power Law: The Relationship of Voltage, Current, and Watts
By Patrick Hoppe
Learners examine three formulas than can be used to find dc power. Examples are given.
By Terry Bartelt
This animated lesson shows the operation of timer-on and timer-off delay relays used in ladder circuit operate.
By Terry Bartelt, Terry Fleischman
The learner will understand how to correctly wire a three-wire sinking and sourcing sensor.
The Silicon Controlled Rectifier
In this animated activity, learners examine the operation of the SCR, including how it is biased and how it is turned off. A brief quiz completes the object.
Series RC Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Parallel RC Circuit Vector and Circuit Analyzer
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Capacitive Reactance Practice Problems
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
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.
Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.
