In this interactive object, learners follow steps to find phase voltages in a partial three-phase power distribution circuit.
Learners follow the steps required to construct an ungrouped frequency distribution using either manual methods or a spreadsheet.
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.
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.
Learners read a brief introduction to in-control and out-of-control conditions and view a series of distribution curves. This is a follow-up to the learning object titled "Quality Basics: Variation."
In this animated object, learners examine the PDF (portable document format), which has become the standard file format in the printing industry for the distribution of printable documents.
In this interactive object, students read about organizing data in a tabular form. A brief quiz completes the activity. This is the first in a series of six learning objects.
