The ampere balance (also current balance or Kelvin balance) is an electromechanical apparatus used for the precise measurement of the SI unit of electric current, the ampere. It was invented by William Thomson, 1st Baron Kelvin. The current to be measured is passed in series through two coils of wire, one of which is attached to one arm of a ...
The International System of Electrical and Magnetic Units is an obsolete system of units used for measuring electrical and magnetic quantities. It was proposed as a system of practical international units (e.g., the international ampere, the international ohm, the international volt) by unanimous recommendation at the International Electrical Congress (Chicago, 1893), discussed at other ...
Ampere balance, an electromechanical apparatus for precise measurement of the ampere; Ampère's circuital law, a rule relating the current in a conductor to the magnetic field around it; Ampère's force law, the force of attraction or repulsion between two current-carrying wires

The Kibble balance is a development of the Ampere balance. The Kibble balance is a more accurate version of the ampere balance , an early current measuring instrument in which the force between two current-carrying coils of wire is measured and then used to calculate the magnitude of the current.
The 2019 revision of the SI defined the ampere by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 × 10 −19 when expressed in the unit C, which is equal to A⋅s, where the second is defined in terms of ∆ν Cs, the unperturbed ground state hyperfine transition frequency of the caesium-133 atom.

The Academy of Sciences of Albania (Albanian: Akademia e Shkencave e Shqipërisë), founded in 1972, is the most important scientific institution in Albania. [1] In the 1980s, several research institutes began at the University of Tirana were transferred to the Academy's jurisdiction. [ 2 ]
The National Library of Albania (Albanian: Biblioteka Kombëtare e Shqipërisë) is Albania's national library headquartered in the country's capital, Tirana. [1] It was founded in 1920 and inaugurated on December 10, 1922. [2] [3]
