Name some sources of direct current


The unidirectional flow of an electric charge is known as direct current. Direct current can flow via conductors like wires, but it can also flow through semiconductors and even a vacuum. Electric current is distinguished from alternating current by the fact that it flows in a constant direction.

Sources of direct current

  • In direct current, the current flows in one direction only. Some sources of direct current are cell, DC generator, etc.
  • Dry cell, dry cell battery, car battery and DC generator, radio and television works only with D.C they have a device in them which convert A.C supplied to them into D.C.
  • The DC current is the current which does not change the direction with time.
