Charge carrier Charge carrier In physics, a charge carrier is a particle or quasiparticle that is free to move, carrying an electric charge, especially the particles that carry electric charges in electrical conductors. Examples are electrons, ions and holes. In a conducting medium, an electric field can exert force on these free particles, causing a net motion of the particles through the medium; this is what constitutes an electric current. In different conducting media, different particles serve to carry charge: It can be seen that in some conductors, such as ionic solutions and plasmas, there are both positive and negative charge carriers,
Duane (given name) Duane (given name) Duane is both a given name for a male, and a family name. It seems to have a convergent etymology from several sources. The name derives from St. Dubhán, a Welsh Saint who established an abbey in Hook Head, Ireland, during the 5th century. As a surname it is O'Dubhain, or Dubhan.
