conductance in Science


  1. A measure of the ability of a material to carry electric current. For direct current, conductance is called conductivity and is equal to 1/R, where R is the resistance of the material. For alternating current, conductance is called admittance. Conductance is measured in mhos. See more at admittance.
  2. See thermal conductance.
