permeability and free
According to Maxwell's equations, the speed of light in a vacuum is a universal constant, dependent only on the electrical permittivity and magnetic permeability of free space.
where is the charge density, which can ( and often does ) depend on time and position, is the permittivity of free space, is the permeability of free space, and is the current density vector, also a function of time and position.
