ΚΠ 1857 W. Thomson in Proc. Royal Soc. 8 546 I have ascertained that the electric conductivity of nickel is similarly influenced by magnetism, but to a greater degree [than iron].] 1858 J. Timbs Year-bk. of Facts 155 By experiments recently made, he [sc. Thomson] has ascertained that the electrical conductivity of nickel is similarly influenced by magnetism. 1922 T. M. Lowry Inorg. Chem. iii. 43 In the special case of water, the best test of purity is to measure its electrical conductivity. This diminishes as the water is purified. 1989 A. C. Davies Sci. & Pract. Welding (ed. 9) I. i. 19 The thermal conductivity is closely allied to the electrical conductivity, that is, the ease with which an electric current is carried by a metal. < as lemmas |
