If two electrodes are sandwitching two dielectric materials with very
different dielectric constants (but the same thickness), say, water
and glass. Would the new dielectric constant lies in between the
original two?
What would be the electric field in between the dielectric materials?
I suppose not half of the total electric field imposed by the
electrodes. Would the larger dielectric constant material take up more
of it?
If the water contains ions, would that change its dielectric constant
from that of its pure form (about 80)?
Is there any relation between dielectric constant and dielectric
strength?
