In electromagnetism, the absolute permittivity, often simply called permittivity and denoted by the Greek letter ε (epsilon), is a measure of the electric polarizability of a dielectric. A material with high permittivity polarizes more in response to an applied electric field than a material with low permittivity, thereby storing … Visa mer The standard SI unit for permittivity is farad per meter (F/m or F·m ). Visa mer The vacuum permittivity ε0 (also called permittivity of free space or the electric constant) is the ratio D/E in free space. It also appears in the Coulomb force constant Visa mer Determining capacitance The capacitance of a capacitor is based on its design and architecture, meaning it will not change with charging and discharging.
