For an insulating material dielectric strength and dielectric loss should be respectively?
For an insulating material dielectric strength and dielectric loss should be respectively
What happens when dielectric breakdown occurs?
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.
What is the material use in the capacitor?
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.
Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.

What materials are naturally static-resistant?
There is no material that is naturally static resistent. The time for which the static charge is present on the material depends on its Relaxation Time. This is directly proportional to the ratio of dielectric constant and its conductivity. Thus conducting materials have very short relaxation time so we feel no static charge is developed on it. Thus for practical purpose most of the metals are static resistant.

What is momentum relaxation time?
Momentum
Relation between relaxation time and mean collision time?
Relaxation time= mean collision time/(1-) where A is the average angle of scattering that the electron makes with its initial direction
At what frequencies the loss highest dielectric is?
As the frequency increases the loss through heat also increases. At relaxation frequency while the dipoles will be just able to align themselves maximum loss is seen. At frequncy above relaxation frequency the dipoles will no longer able to keep up change with applied field. They become frozen.
What does it mean to have a dream of hanging out with friends?
Not all dreams have deep significance. A dream of hanging out with friends represents the relaxation and pleasure of hanging out with friends.
Why collision time and relaxation time are not equal in anisotropic medium?
average time, an electron spends between two successive collision, is called relaxation time and time spent by electron at point of contact, is called collision time
