👉 kbar is a unit of measurement used to express the electrical resistance of an object. It is defined as: \[ kbar = 1/\sqrt{2\pi \epsilon_0 R}\] where: - \( kbar \) is the electric constant, equal to approximately 8.99 x 10^9 N/m² K⁻⁴ - \( \epsilon_0 \) is the permittivity of free space, approximately 8.85
