PPT-Resistivity

Learning objectives Candidates should be able to a define resistivity of a material b select and use the equation c describe how the resistivities of metals and semiconductors are affected by temperature. The resistivity may be used to determine the dielectric breakdown dissipation factor moisture content mechanical continuity and other important properties of a material The volume resistivity of some insulators such as sapphire and Teflon can be as a landslide . monitoring system using electrical resistivity tomography.
