Power Systems
...
| A power system converts, transmits, and controls energy to perform useful work. A machine such as a lawn mower is a relatively small power system with few parts and few end tasks. Some power systems are very large, and have many parts and end tasks. An example would be an electric power plant and transmission system, which may serve millions of people and have parts extending over hundreds of miles. |
