Question
Two prime symbols denote this quantity's imaginary part, which is divided by its real part to give the electric loss tangent. The index of refraction in non-magnetic materials is proportional to the square root of this quantity. After factoring out a value with units of newtons per ampere-squared, one side of Ampere's law can be written as "J plus [a value for this quantity] times d-E-d-t." A unitless "relative" form of this quantity equals this quantity divided by (*) 8.8 picofarads per meter and is synonymous with the dielectric constant. The Coulomb constant is the reciprocal of four-pi times this quantity for the vacuum. For 10 points, name this quantity denoted epsilon that is not to be confused with permeability. ■END■
ANSWER: permittivity [or absolute permittivity or relative permittivity or vacuum permittivity or permittivity of free space or electric permittivity; prompt on dielectric constant before read by asking "the dielectric constant is a ratio of values for what quantity?"; prompt on epsilon or epsilon-naught before "epsilon" is read] (Index of refraction equals the square root of the product of relative permittivity and relative permeability, but relative permeability is near one in non-magnetic materials.)
