Students read an introduction to transformers that includes schematic symbols, turns ratios, mutual inductance, and the coefficient of coupling.

Students read how to determine the elevation of an alignment or cross section where it crosses the TIN.

Learners study the operation of a ladder circuit in which coils on one rung control contacts in other rungs.

In this animated learning object, students examine the addresses of PLC elements and how they pertain to I/O connections and internal memory files.

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.
