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.
