Specific resistance sentence example

specific resistance
  • Unfortunately the effects of magnetization upon the specific resistance of bismuth vary enormously with changes of temperature; it is therefore necessary to take two readings of the resistance, one when the spiral is in the magnetic field, the other when it is outside.

  • Moreau (C. R., 1900, 130, pp. 122, 412, 562) that if K is the coefficient of the Hall effect (I) and K' the analogous coefficient of the Nernst effect (i.) (which is constant for small values of H), then K' = Ka/p, v being the coefficient of the Thomson effect for the metal and p its specific resistance.
