plane waves in lossy dielectrics
For an insulating material dielectric strength and dielectric loss should be respectively
The dielectric,usually the insulator between the plates of a capacitor, can be overstressed by the application of too high voltages applied to the capacitor plates. The dielectric breaks down and a current flows between the plates until,either they are discharged, or an equilibrium is reached,below the working voltage of the capacitor. If the dielectric is damaged in this process he capacitor must be replaced. Some dielectric material self heal and can recover from an over voltage.
Capacitors are named after their dielectrics. So, an 'air capacitor' uses air as its dielectric, a 'mica capacitor' uses mica as its dielectric, and so on. There are lots of different dielectric used to separate the plates of a capacitor, each with different permittivities and dielectric strengths. As the perfect dielectric (i.e. one with both a very high permittivity and a very high dielectric strength) doesn't occur, the choice of dielectric is always a compromise between it permittivity and dielectric strength.
No, these are two unrelated properties of a material.

Lossy
they are lossless...
JPG's not too bad but GIF is terribly lossy
Lossy= You lose somedata Lossless= You dont
shush
For an insulating material dielectric strength and dielectric loss should be respectively
In case of a lossy capacitor, its series equivalent resistance will be large.
dielectric constant
For an insulating material dielectric strength and dielectric loss should be respectively high or low
why need dielectric test for transformer
lossless
