Good thing Wikipedia has that "Derivation" tab to let you know where the law comes from.bentzy said:An empirical law doesn't explain a phenomenon on its basic mechanism/s, but just gives the relation between variables.
Electrical conductivity is the measure of a material's ability to conduct an electric current. It is typically measured in siemens per meter (S/m) or mho per meter (mho/m), with higher values indicating better conductivity.
Electrical conductivity refers to a material's ability to conduct electricity, while thermal conductivity refers to its ability to conduct heat. While both involve the transfer of energy, they are separate properties and are measured in different units.
Electrical and thermal conductivities are affected by a variety of factors, including the material's composition, temperature, and the presence of impurities or defects. In general, materials with high electrical conductivity also have high thermal conductivity.
Electrical and thermal conductivities play a crucial role in many aspects of everyday life, from powering our devices and homes to regulating the temperature of our food and drinks. They also have important applications in industries such as electronics, transportation, and construction.
Yes, electrical and thermal conductivities can be altered through various methods such as doping, alloying, and heat treatment. These techniques can be used to improve the performance of materials in specific applications or to create new materials with desired properties.
