The Planck current is the natural unit of electrical current, denoted by Ip. Image File history File links 1 - conductors, Fp - Planck force, lp - Planck leght, Ip - Planck current. ... In physics, Planck units are physical units of measurement originally proposed by Max Planck. ... In electricity, current refers to electric current, which is the flow of electric charge. ...

is the Planck charge In physics, the Planck charge is the natural unit of electric charge, denoted by . ...


is the Planck time The Planck time is the natural unit of time, denoted by tP. It is considered the smallest possible measurement of time. ...

G is the gravitational constant According to the law of universal gravitation, the attractive force between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them. ...


c is the speed of light in vacuum. Cherenkov effect in a swimming pool nuclear reactor. ...


The Planck current is that current which, in a conductor, carries a Planck charge in Planck time. It has been suggested that Conductor (power engineering) be merged into this article or section. ...


Alternately, 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. Infinity is a term with very distinct, separate meanings which arise in theology, philosophy, mathematics and everyday life. ... This article is about absence of matter. ... In physics, force is defined as the time derivative of momentum: F = dp/dt = d(m·v)/dt where F is the force (a vector quantity), p is the momentum, v is the velocity, and m is the mass. ...

Max Planck - Wikipedia, the free encyclopedia (2669 words)
By interpolating between the laws of Wien and Rayleigh-Jeans Planck found the famous Planck fl-body radiation law which described the experimentally observed fl-body spectrum very well; it was first proposed in a meeting of the DPG on October 19, 1900 and published in 1901.
Planck and Nernst, in order to clarify the increasing number of contradictions, organised the First Solvay Conference (Brussels 1911); at this meeting Einstein was finally able to convince Planck.
In 1938, Planck celebrated his eightieth birthday; the DPG held an official celebration, during which the Max-Planck medal (founded as the highest medal by the DPG in 1928) was awarded to French physicist Louis de Broglie - one year before the outbreak of a new war between France and Germany.
