Glossary


Electrical processes and systems govern much of our technically oriented daily lives, but they are just as important in natural systems.

The study of electricity allows us to apply analogical reasoning. We will describe electrical systems just as we did hydraulic ones.

The coupling of hydraulic, electrical, and gravitational processes will introduce us to the role of energy in physical processes.
