What is direct current?

  • the type of current that is supplied to the home by power utilities
  • the type of electric current in which the current flow periodically reverses direction
  • the type of current that is produced by batteries, computer power supplies, and solar cells
  • the type of current that is represented by a sine wave

Explanation: Direct current is the flow of electricity that does not change direction. Direct current is used by computers and other digital devices. It is created by batteries, DC power supplies, and solar panels. Alternating current is the flow of electricity that reverses direction periodically. Because of this, its representation is a sine wave. It is delivered to homes and businesses by power utilities.
