DC Power Sources

“DC Power Sources” provides a foundational overview of direct current and the different power sources that produce it. A DC power source is any means used to convert various forms of energy into DC electricity. DC power sources include batteries, fuel cells, solar cells, and DC generators. Most DC power is supplied by batteries, but generators are used for some applications. Fuel cells and solar cells are not widely used but may be more popular in the future if they can be made less expensive and more efficient. After taking this class, users will be familiar with different methods of producing DC power and other important concepts, such as magnetic induction. This is important for working with electrical systems because many electrical devices operate on direct current. In addition, DC may become more popular in the future if alternative sources such as fuel and solar cells become more cost-effective.
