Planck current
The Planck current is the unit of electric current, denoted by IP, in the system of natural units known as Planck units.
- ≈ 3.479 × 1025 A
where:
- is the Planck charge
- is the Planck time
- = permittivity in vacuum
- is 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.
