The speed of light in vacuum is the speed at which all massless particles and changes of the associated fields (including electromagnetic radiation such as ... more
Capacitance is the ability of a body to store an electrical charge. Any object that can be electrically charged exhibits capacitance. Concentric or ... more

The cross section is an effective area that quantifies the intrinsic likelihood of a scattering event when an incident beam strikes a target object, made ... more
The refractive index is used for optics in Fresnel equations and Snell’s law; while the relative permittivity and permeability are used in ... more
First proposed by Clement D. Child in 1911, Child’s law states that the space-charge limited current (SCLC) in a ... more
In classical electromagnetism, polarization density (or electric polarization, or simply polarization) is the vector field that expresses the density of ... more
The Gilbert model assumes that the magnetic forces between magnets are due to magnetic charges near the poles. This model produces good approximations that ... more
