The Planck current is the unit of electric current, denoted by IP, in the system of natural units known as Planck units. $\approx 3.479 \times 10 A$, where: the Planck time is the permittivity in vacuum and the reduced Planck constant G is the gravitational constant c is the speed of light in vacuum. The Planck current is that current which, in a conductor, carries a Planck charge in Planck time. Alternatively, the Planck current is that constant current which, if maintained in two straight parallel conductors of infinite length and negligible circular cross-section, and placed a Planck length apart in vacuum, would produce between these conductors a force equal to a Planck force per Planck length.
