Comparison between AC and DC methods
DC methods measure resistance directly using a constant voltage, providing a single measurement without frequency dependency. They are simple but may lack sensitivity for materials with nonlinear conductivity. AC methods measure impedance with varying frequencies, offering frequency-dependent information and higher sensitivity. They are more versatile but require specialized equipment. The choice depends on material properties, accuracy needs, and measurement requirements.
Electrical Conductivity
Electrical conductivity is a fundamental property that measures a material’s ability to conduct electric current. It varies among materials and is influenced by factors such as temperature, material composition, impurities, and pressure. Electrical conductivity is typically measured in siemens per meter (S/m).
Electrical conductivity finds applications in electronics, power transmission, material science, environmental science, geology, biomedical fields, and more. In this article, we learn about electrical conductivity in detail.
