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.
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 an explanation of power factor in a power distribution and how it can be improved by using a power factor correction capacitor bank. A brief quiz completes the activity.
Students read an explanation of reactive power in a power distribution system involving motors, generators and transformers. A brief quiz completes the activity.
Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.
In this animated activity, learners see that changing the resistance value of the load in the secondary of a transformer causes current to vary in the primary.
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.
