41. Sometimes the conductivity, the reciprocal of the resistivity , is quoted instead. 42. A wide range of typical soil resistivity values can be found in literature. 43. Palladium resistivity depends on the fraction of dissolved hydrogen. 44. And the 25�C is important : the resistivity changes a lot with temperature. 45. The work was also the first ever use of airborne resistivity in Antarctica. 46. This makes uncertain the absolute resistivity value for curium ( about 125 ���cm ). 47. A semiconductor is a material that has a resistivity between a metal and insulator. 48. Resistivity is a measure of the material's ability to oppose electric current.49. A low resistivity indicates a material that readily allows the flow of electric current. 50. Resistivity is commonly represented by the rho ).
