1885 Heaviside in Electrician 4 Sept. 311/1 ‘Specific resistance’ may well be called ‘resistivity’, and specific conductance ‘conductivity’, referring to the unit volume. Resistivity is the reciprocal of conductivity, and resistance of conductance.
1886 Heaviside in Electrician 29 Jan. 228/1 ‘Resistivity’ for specific resistance, and ‘conductance’ for what is sometimes called the conductibility of a wire, i.e., not its conductivity (specific conductance), but the reciprocal of its resistance.
1892 O. Heaviside Electr. Papers I. 399 Let a cable be constructed according to the following simple specification:—Its electrostatic capacity to vary in simple proportion to the distance from one end O. Its conductance to vary in simple proportion to the distance from O. Note, ‘Conductance’ is here substituted for ‘conductivity’. It means the reciprocal of the resistance.
1892 T. O'C. Sloane Standard Electr. Dict. (1893) 144 Conductance, the conducting power of a given mass of specified material of specified shape and connections... Conductance is an attribute of any specified conductor, and refers to its shape, length and other factors. Conductivity is an attribute of any specified material without direct reference to its shape or other factors.
1904 N. H. Schneider Man. Electr. Plants 1 The power of conducting is generally conductance, or conductivity.
1926 P. B. Hawk & O. Bergheim Pract. Physiol. Chem. (ed. 9) 38 The blood and bile of most mammals..possess considerably higher conductances than milk and saliva.
1941 S. R. Roget Dict. Electr. Terms (ed. 4) 68/1 Conductance, the reciprocal of Resistance or, in the case of alternating current, the energy component in the reciprocal of Impedance.
1966 C. F. Stevens Neurophysiol. ix. 117 It is customary to specify the ease with which a type of ion passes through the [nerve cell] membrane by the magnitude of the conductance for that ion.
