The higher the dielectric constant, the higher the capacitance right?
I am reading that water has a dielectric constant of 80. This means the capacitance is 80 times greater (if there was water between the parallel plate capacitor) than if the capacitor was in vacuum.
What is the dielectric constant of a conductor? Say copper? Since it allows current flow, would it have a negative dielectric constant?
If so, then a dielectric constant = -inf would be a perfect conductor? dielectric constant of inf would be a perfect insulator?
