Title: Describe the concept of AC.
Course: Mechatronics I (13901-I) > Section: Introducing Electrical Systems

Description should include

- how voltage and current varies as time passes
- the difference between single phase and three phase
- root mean square (RMS) vs. peak voltage.

Process/Skill Questions:

- Why is AC used to distribute most of the utility power in the world?
- How fast does the voltage fluctuate? How does that vary from the U.S. to other places in the world?
- Where would a three-phase power be found?
