conductance
  هازایی   
hâzâyi

Fr.: conductance   

The ability of a system to conduct electricity, calculated as the ratio of the current which flows to the potential difference present. This is the reciprocal of the → resistance, and is measured in → siemens or → mhos.

conduct + → -ance.

conduction
  هازش   
hâzeš

Fr.: conduction   

The transference of energy through a body, without visible motion of any part of the body. → induction; → reduction; → subduction; → transduction.

  الکترون ِ هازش   
elektron-e hâzeš

Fr.: électron de conduction   

An electron whose energy lies in the conduction band of a solid, where it is free to move under the influence of an electron field.

conduction; → electron.

conduction band
  باند ِ هازش   
bând-e hâzeš

Fr.: bande de conduction   

In the energy spectrum of a solid, a range of energies in which electrons can move freely under the influence of an electrical field. Metals have many electrons in this range, insulators have none. In semiconductors the conduction band contains few electrons provided by impurity atoms or ejected from the valence bands by thermal energy or photon absorption.

conduction; → bande.

conductive
  هازنده

Fr.: conducteur   

(Adj.) Having the property or capability of conducting.

From → conduct + -ive a suffix of adj.

conductivity
  هازندگی   
hâzandegi

Fr.: conductivité   

1) General: A measure of the ability to transmit, as electricity, thermal energy, sound, and so on.
2) → electrical conductivity.
3) → thermal conductivity.

From → conductive + → -ity suffix forming abstract nouns expressing state or condition.

conductor
  هازنده   
hâzandé

Fr.: conducteur   

Substance, or body, which offers a relatively small resistance to the passage of an electric current.

Agent noun from conduce, → conduct, + → -tor.

cone
  مخروط   
maxrut (#)

Fr.: cône   

A solid bounded by a plane and the surface generated by a straight line which always touches a simple closed curve on the plane and passes through a fixed point not on the plane.

L. conus "a wedge, peak, cone," from Gk. konos "cone, spinning top, pine cone," from PIE base *ko(n)- "to sharpen."

Maxrut from Ar.
