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 ampere rapidly gained support over the ohm, as many national standards laboratories were already realizing the ampere in absolute terms using ampere balances. [ 16 ] [ 20 ] The International Electrotechnical Commission (IEC) adopted the Giorgi system with the ampere replacing the ohm in 1935, and this choice of base units is often called ...
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
As of the 2019 revision of the SI, the ampere is defined by fixing the elementary charge e to be exactly 1.602 176 634 × 10 −19 C, [6] [9] which means an ampere is an electric current equivalent to 10 19 elementary charges moving every 1.602 176 634 seconds or 6.241 509 074 × 10 18 elementary charges moving in a second.
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 abampere was coherent with the emu-cgs system, in contrast to the ampere, the practical unit of current that had been adopted too in 1875. The emu-cgs (or "electromagnetic cgs") units are one of several systems of electromagnetic units within the centimetre–gram–second system of units ; others include esu-cgs, Gaussian units , and ...
He was shot in the back in 1918 at the age of 65 by Austro-Hungarian forces in Qafa e Markofqes, in the mountain of Gjarpri in today's Kukës County. [11] [12] [13] He was a close friend and related to Isa Boletini. He is a venerated figure in Albania and Kosovo. [14] He also helped Bajram Curri open up a school in Krasniqe. [15]
The Republic of Central Albania (Albanian: Republika e Shqipërisë së Mesme) was a short-lived unrecognised state established on 16 October 1913, with its administrative centre in Durrës, today in Albania. [2]
