👉 In physics, a permittivity (or electric permittivity) is a quantity that measures the resistance of an object to change its electrical charge. It's defined as the ratio of the force of repulsion between two charges and their distance from each other. The permittivity can be calculated using the following formula: \[ \epsilon = \frac{F}{4\pi k_{e}r^2} \] where: - \( F \) is the electric force acting on
