Dielectric strength is a coating’s ability to endure an applied voltage without breakdown. This parameter is the highest voltage (typically stated in volts per mil thickness) at which no dielectric breakdown occurs. It quantifies how strong a conformal coating’s insulation is, with a higher nu...
aThe panel consists of two glass plates. The front plane with 2 parallel transparent electrodes (row and sustain, made of Indium Tin Oxide) faces the viewer. An insulation layer, covered by MgO acting as dielectric. On the backplane, the column electrode is placed, often made by Ag by phot...
The dielectric constant of air is very close to the dielectric constant of vacuum. This is why neither vacuum nor air increase the capacitance of a capacitor. On the other hand, solid dielectric substances such as polyethylene or glass, which have a higher dielectric constant, can sustain perman...
It is the opposite reaction induced in a component to resist its deformation during the application of load into the element. The stress can be calculated easily by the fraction of the applied load to the area of the component. The stress-induced in the body is linearly varying with ...
Hipot Test is short name of high potential (high voltage) Test and it is also known asDielectric Withstand Test. A hipot test checks for “good isolation”. Hipot test makes surety of no current will flow from one point to another point. Hipot test is the opposite of a continuity test...
Complex dielectric constant:The complex dielectric constant is a physical quantity that express the capability of materials to withstand external fields that have a strong dependence from the frequency.Answer and Explanation: The term, complex dielectric constant, is basically employed in order to ...
The circuit breaker has to carry large rated or fault power. Due to this, there is always dangerously high arcing between moving contacts and fixed contact during operation. This arcing can be safely quenched if thedielectric strengthbetween the current-carrying contacts increases rapidly during every...

Temperature: The dielectric constant generally increases with temperature as the increased thermal motion of the molecules in the material leads to more polarization. Density: The dielectric constant of a material is inversely proportional to the density of the material. As the density decreases the di...
This is correct if we neglect the “end effect”. This “end effect” is the dielectric effect of the air at the end of the antenna that increases the effective length of the antenna. Due to the end effect, an antenna wire acts as 5% longer than the actual length. This will produce ...
