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.
How you reduce capacitor size while keeping the capacitance?
You can reduce the size of the plates (thus making the capacitor smaller physically) if you also do one or both of the following:move the plates closer together (which also reduces size, but lowers the breakdown voltage)use a dielectric with a higher dielectric constantOf course these changes must be made at the time of manufacture, they cannot be done to change an existing capacitor.
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 is signal distortion in transmission lines?
there are some distortion in transmission line : copper loss,dielectric loss,skin effect
What type of electrical bridge can be used for the measurement of dielectric loss of a capacitor?
Schering bridge
How do mutual funds reduce the risk of loss?
Mutual fund do not reduce the risk of loss.
How Hollow conductor is used to reduce corona loss how does it reduce the loss?
to have large diameter without increasing its weight.
What help the fish body to reduce water loss?
The scales on the fish body helps it to reduce water loss.
Can you reduce pressure loss and friction loss on pipelines with electricity?
no you can not
What is being done to reduce the loss of the stratospheric ozone?
To reduce ozone loss, CFC's are banned. They react with ozone to deplete it.
