Direct Current

Credits
Scroll to top Direct Current
Direct Current, or DC Electricity is produced from batteries and solar cells. DC power flows in a constant, negative to positive flow. This is due to the fact that there are no moving parts, such as in a generator. Most electronic devices run on DC power because the electricity must be specific and constant.
