Question

What is the dielectric constant of silver?

Answer 1

Answer:

Dielectric constant of silver is 1.5eV to 3eV

Answer 2

The dielectric constant of silver lies between 0.188 to 1.937 mm.

• Dielectrics are materials that do not conduct electricity.
• They act as insulators that have no free electrons.
• So, when an electric field is applied to dielectrics, the dielectric materials easily become polarized.
• Thus, their behaviour in an electric field is different from that of conductors.
• Moreover, silver is a dielectric material.
• In the presence of an electric field, silver becomes polarized and it is used to boost the capacitance of the capacitor.
• However, according to the theoretical model, the dielectric constants of the silver at 432.8 and 632.8 nm are ε = − 5.19 + i 0.28 and ε = − 16.32 + i 0.54.
