In SI, the unit of dielectric strength is volts per meter (V/m). It is also common to see related units such as volts per centimeter (V/cm), megavolts per meter (MV/m), and so on. In United States customary units, dielectric strength is often specified in volts per mil (a mil is 1/1000 inch). The conversion is: $${\displaystyle … See more In physics, the term dielectric strength has the following meanings: • for a pure electrically insulating material, the maximum electric field that the material can withstand under ideal conditions without undergoing See more The field strength at which break down occurs depends on the respective geometries of the dielectric (insulator) and the electrodes with which the electric field is applied, as well as … See more • Breakdown voltage • Relative permittivity • Rotational Brownian motion • Paschen's law - variation of dielectric strength of gas related to pressure See more Electric current is a flow of electrically charged particles in a material caused by an electric field.
