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 thermal loss in dielectric heating?
Thermal loss in dielectric heating refers to the energy that is dissipated in the form of heat due to the electrical resistance of the dielectric material. This heat loss can reduce the overall efficiency of the heating process and may lead to overheating issues if not properly managed. Techniques such as choosing appropriate dielectric materials and optimizing the design of the heating system can help minimize thermal losses.

For an insulating material dielectric strength and dielectric loss should be respectively
For an insulating material dielectric strength and dielectric loss should be what?
high and high
For an insulating material dielectric strength and dielectric loss should be respectively high or low?
For an insulating material, the dielectric strength should be high to withstand high voltages without breaking down. Conversely, the dielectric loss should be low to minimize energy loss due to internal friction within the material when subjected to an electric field.
Why dielectric loss increases with temperature?
Dielectric loss increases with temperature because at higher temperatures, molecules in the dielectric material vibrate more vigorously, leading to increased collisions and energy dissipation. This increased molecular motion results in higher internal friction within the material, causing a rise in dielectric loss.

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
Is water a good dielectric?
Yes, water is a good dielectric because it has a relatively high dielectric constant compared to other substances. This property allows water to effectively reduce the strength of electric fields and act as an insulator in many applications, such as in capacitors and electrical systems.
How do mutual funds reduce the risk of loss?
Mutual fund do not reduce the risk of loss.
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 help the fish body to reduce water loss?
The scales on the fish body helps it to reduce water loss.
