What's the difference between convection and current?

Convection


Definition:

  • (n.) The act or process of conveying or transmitting.
  • (n.) A process of transfer or transmission, as of heat or electricity, by means of currents in liquids or gases, resulting from changes of temperature and other causes.

Example Sentences:

Current


Definition:

  • (a.) Running or moving rapidly.
  • (a.) Now passing, as time; as, the current month.
  • (a.) Passing from person to person, or from hand to hand; circulating through the community; generally received; common; as, a current coin; a current report; current history.
  • (a.) Commonly estimated or acknowledged.
  • (a.) Fitted for general acceptance or circulation; authentic; passable.
  • (a.) A flowing or passing; onward motion. Hence: A body of fluid moving continuously in a certain direction; a stream; esp., the swiftest part of it; as, a current of water or of air; that which resembles a stream in motion; as, a current of electricity.
  • (a.) General course; ordinary procedure; progressive and connected movement; as, the current of time, of events, of opinion, etc.
