dielectric constant
This term is a technical specification used primarily in physics and electrical engineering to describe the insulating properties of a material. It is a relative value, meaning it compares the material's permittivity to that of a vacuum, which serves as the baseline. High values indicate a greater capacity to store charge, which is critical for the design of capacitors.
Because it is a specific scientific measurement, the term is used in a formal, academic, or industrial register. It is almost never used in casual conversation and typically appears in the context of material science, electromagnetism, or chemical analysis of solvents.
