A conductor behaves like a medium of infinite dielectric constant, so for silver k=∞k=\infty.

The dielectric constant k=E0Ek=\dfrac{E_0}{E}, where E0E_0 is the applied field and EE is the net field inside the material. In a conductor such as silver, free electrons rearrange themselves until the field inside becomes zero, i.e …
