Electric permittivity of copper

[mike217]

Can anybody please tell me where I can find the value for the relative permittivity of copper with respect to air.

Thanks

for your question. The electric permittivity of copper, also known as the dielectric constant, is a measure of a material's ability to store electric charge. It is typically denoted by the symbol ε and is a dimensionless quantity. The relative permittivity of copper with respect to air is a specific value that indicates how much more or less charge can be stored in copper compared to air.

The value for the relative permittivity of copper with respect to air can be found in various sources such as material datasheets, engineering handbooks, and online databases. One reliable source is the National Institute of Standards and Technology (NIST) website, which provides a comprehensive list of material properties including the relative permittivity of copper with respect to air. Another option is to consult with a materials engineer or physicist who specializes in electrical properties.

It's important to note that the relative permittivity of copper can vary depending on factors such as temperature, frequency, and impurities in the copper. Therefore, it is best to use a specific value for your specific application or to consult with an expert to determine the most accurate value for your needs. I hope this helps answer your question.
