Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.
Where is the knowledge of dielectric strength helpful?
One field in which this is helpful is in the manufacture of insulating materials. Dielectric strength determines the strongest electric field an insulator can withstand before it fails. For example, if the insulation around a wire melts or breaks, the insulator's dielectric strength is compromised.
Can the dielectric constant of carbon in water be measured?
dielectric constant is a property of a material, this question is asking the property of a two mixed together, in an undeclared ratio. But yes dielectric constants can be measured. The problem you will have is keeping a uniform mix.
How capacitor is used to check freshness of fish?
Between the two plates of a capacitor lies a medium with a specific dielectric constant. Placing a fish between these plates changes to dielectric constant. If the fish is fresh it will be strong and tight, thus possessing a higher dielectric constant. If the fish is older, it's dielectric constant, or body, will be weaker due to decay.
What is the effect of temperature on dielectric constant of a dielectric?
Usually, dielectric materials have permanent dipoles. As temperature increases, the molecules in the dielectric have more thermal energy and therefore, the amplitude of random motion is greater. This means that the molecules are less closely aligned with each other (even in the presence of an electric field). Hence, the dielectric constant reduces.
What is the die electric constant for insulators?
There is no more the dielectric constant for insulators than the colour for shirts. Every shirt has a colour, and every insulator has a dielectric constant. Find out what material your insulator is, then look in Kaye & Labey or any good handbook for radio and electronics engineers.
What is dielectric constant in chemical terms?
dielectric constant
What is the sodium hypochlorite dielectric constant?
dielectric constant for sodium Hypochlorite
Dielectric constant of metal is?
The dielectric constant varies, depending on the material.
What is the insulator in a coaxial cable called?
It's called the Dielectric
What is relative permittivity if dielectric constant of water is 80.10?
'Dielectric constant' is an archaic term for relative permittivity. They are one and the same.
Why does dielectric constant decrease with an increase in temperature?
If the temperature increases, the conductivity will increase too which means the dielectric constant is reduced
Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.
What is the dielectric constant of Silver?
infinite
What is dielectric matter?
An electrical insulator that can be polarized by an external electric field.
Why such materials are good insulators?
Dielectric meterials are good insulator materials
