      Electronics (Electron Mechanics) refers to the flow of charge (moving
      electrons) through nonmetal conductors (mainly semiconductors), whereas
      electrical refers to the flow of charge through metal conductors. For
      example, flow of charge through silicon, which is not a metal, would
      come under electronics; whereas flow of charge through copper, which is
      a metal, would come under electrical. This distinction started around
      1906 with the invention by Lee De Forest of the triode. Until 1950 this
      field was called "Radio techniques" because its principal application
      was the design and theory of radio transmitters and receivers.

      The study of semiconductor devices and related technology is considered
      a branch of physics whereas the design and construction of electronic
      circuits to solve practical problems comes under electronics
      engineering. This article focuses on engineering aspects of electronics.
