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 about the concept of true power and view examples of how it is dissipated as heat is provided.
Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.
The learner will solve problems using the rule for multiplying powers that have the same base.
