In this animated learning object, users view the process of entering a formula in an Excel spreadsheet. Several different methods and associated examples are given.

Students follow steps to determine the number of inputs that can be driven by a specific IC. A sample problem is given.

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

In this learning activity you'll read introduction to electrical quantities, units, and symbols and test their knowledge in a matching exercise.
