# Dielectric Constant Calculation

**Formula:** `Κ = C_with_dielectric / C_without_dielectric`

The dielectric constant (Κ) of a material is a measure of its ability to store electrical energy in an electric field. It is defined as the ratio of the capacitance of a capacitor with the dielectric between its plates (C_with_dielectric) to the capacitance of the same capacitor without the dielectric (C_without_dielectric). The dielectric constant is a dimensionless quantity and provides an indication of a material’s insulating properties. It has important applications in designing capacitors and understanding the behavior of circuits with insulating materials.
