TOPIC 1: ENERGY
Energy is the ability to do work. It exists in a number of different forms and can be converted from one form to another. Our bodies use these energy conversion processes, as do a number of technologies. An understanding of energy conversion allows us to use energy efficiently to do work.
TOPIC 2: ELECTRIC ENERGY
Energy doesn’t just appear out of nowhere; we have many technologies that serve to convert different sources of energy into electrical energy, which we can then use to do work. No electrical system is 100% efficient at this conversion process, though. Here, you will learn how to evaluate different electrical technologies in terms of their power & efficiency.
