Define Direct current and give some examples of it

Direct current is the unidirectional flow of an electric charge. Direct current may flow through conductors such as a wire, but can also flow through semiconductors, or even through a vacuum. The electric current flows in a constant direction, distinguishing it from alternating current. Following are some of the examples of DC current:

  • The mobile battery gives DC
  • The laptop battery gives DC
  • Solar panels provide DC
  • Power Banks provide DC
