Water is a fine dielectric. One of the main issues is that it ionizes certain materials. If it comes in contact with metals, some ions may be leached into the water. This thus raises the conductivity of the water.
Good dielectrics are bad conductors. This helps the capacitor store more charge. If the water becomes conductive, it fails as a good dielectric.
What else can I help you with?
How does the moisture and temp effect the breakdown strength solid dielectric?
Generally, increased moisture levels will lower breakdown strength, especially if the dielectric readily absorbs water. Increasing temperature generally decreases breakdown strength of solid dielectrics. The dielectric strength of some materials may increase with temperature within limited temperature ranges. However, dielectric strength eventually begins to decrease at higher temperatures.
Why is the dielectric strength of vacuum infinite?
The dielectric strength of vacuum is infinite because there is no molecule in the vacuum.
What is a bounded medium?
a bounded medium is a connection that used wires... the medium is the form of connection and bounded simply means that it is a wired connection!
Medium for the wave?
The medium of any wave is the material that the wave energy travels through; in this case water.
What is the speed of light in vacuum divided by the speed of light in medium?
The speed of light in a vacuum is 186,000 miles per second and the speed of sound at 70 degrees F at sea level is approx. 1100 feet per second. Do the math. You should come up with something around 879 thousand. (a ratio, with no units)
What is the unit for the dielectric constant of a medium?
The unit for the dielectric constant of a medium is a dimensionless quantity as it represents the ratio of the permittivity of the medium to the permittivity of a vacuum.
What is the name of the fitting used to connect the water lines to the water heater?
Dielectric union
What is dielectric medium?
It is the same everywhere and in all directions.
By desauty bridge find the dielectric constantof a medium?
yes
What is homogeneous dielectric medium?
It is the same everywhere and in all directions.
When a medium behave like dielectric?
When a medium behaves like a dielectric, it means that it can become polarized in the presence of an electric field. This polarization results in the medium experiencing forces and interactions with the electric field, affecting the overall behavior of the system. Dielectric materials are characterized by their ability to store electrical energy in the form of electric field-induced polarization.
What is the ratio of forces between two masses kept at a certain distance in the air to the force between them when kept in any other medium?
The ratio of forces between two masses in air to the force between them in any other medium is determined by the medium's relative permittivity or dielectric constant. In a medium with a dielectric constant other than air, the force between the masses will be reduced by a factor equal to the medium's dielectric constant.
How does force between 2 point charges changes if the dielectric constant of medium in which they are kept increases?
If the dielectric constant of the medium between the charges increases, the force between the charges decreases. This is because increasing the dielectric constant reduces the electric field strength between the charges, leading to a decrease in the force between them.
What is dielectric constant?
A dielectric is an insulating material that does not conduct electricity and is transparent to an electromagnetic field. Dielectric materials are used to separate conducting surfaces such as the plates inside a capacitor, wires inside transformers, electric cable conductors, and elsewhere in the electric industry where electrical separation of charged elements is necessary. The dielectric constant is a ratio of the capacitance of a capacitor in which a particular insulating material is the dielectric, to the capacitance of the capacitor in which a vacuum is the dielectric.
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 Relative dielectric constant for vacuum?
YES IT IS. Any quantity which is ratio of two physical quantities having same unit is dimensionless. Dielectric constant is ratio of Permittivty of medium to the permittivity of free space. As Permittivity of medium and permittivity of free space both have same units(F/m ie Farad/meter) dielectric constant becomes dimensionless quantity
Can water be used as a contrast medium?
no
