Why can't metal be used as a dielectric in a capacitor?
A metal can transmit the electron and the force so it is not a dielectric to electrons.
How water is dielectric constant?
The dielectric constant of water varies with temperature and is approximated by this polynomial equation: E = 87.740 - 0.40008*t + 9.398*(10^-4)*t^2 - 1.410*(10^-6)*t^3
For an insulating material dielectric strength and dielectric loss should be respectively high or low?
For an insulating material dielectric strength and dielectric loss should be respectively high or low
What is thermal loss in dielectric heating?
Thermal loss in dielectric heating
What is the dielectric breakdown strength?
This depends on the particular dielectric. Each has a different breakdown strength.
Why water is not used as a dielectric medium?
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 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 such materials are good insulators?
Dielectric meterials are good insulator materials
What is the effect of dielectric constant of water on the solubility of the ionic salt?
Water has a very high dielectric constant so when an ionic salt is placed in water it ionizes and water molecules react with ions of solute and make a solution
What is the name of the fitting used to connect the water lines to the water heater?
Dielectric union
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.
Why can't metal be used as a dielectric in a capacitor?
A metal can transmit the electron and the force so it is not a dielectric to electrons.
Which dielectric in this world has highest dielectric constant?
Strontium Titanate has a dielectric constant of 233. TDK in Japan makes Ultra-high Voltage Ceramic Capacitors using this as the dielectric material. Compared to distilled water at 76.7 - 78.2 (lowers as temperature rises). Types of glass can vary between 4 and 10.
What are some examples of a chemical property for water?
It has a very high dielectric constant
How water is dielectric constant?
The dielectric constant of water varies with temperature and is approximated by this polynomial equation: E = 87.740 - 0.40008*t + 9.398*(10^-4)*t^2 - 1.410*(10^-6)*t^3
Why do polar substance have a high dielectric constant?
Water, due to its polar nature, has a large dielectric constant. Therefore, water molecule has a very large electric dipole moment and is forced to rotate to respond to an alternate external electric field. Hence water as a liquid has a very large dielectric constant i.e. 80. Mica on the other hand is less polar as water and hence has low dielectric constant.
What dielectric materials are good thermal conductors?
The best example of a dielectric with good thermal conduction is diamond, which is almost a perfect dielectric, but also has a thermal conductivity (up to 41kW·m−1·K−1) that is better than most metals (e.g. silver has a thermal conductivity of 0.430kW·m−1·K−1).
