Students review the Voltage Divider Rule and work practice problems.

Learners study animated rheostat settings that show how varying the current flow affects the amount of power that is dissipated in a series circuit. Nine review questions complete the activity.

This primer introduces the student to the proper use of the exponent (EE) function on a TI-86 calculator.

Students view a demonstration of the Current Divider Rule with the use of complex numbers. Examples are given.

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.
