The abcoulomb (abC or aC) or electromagnetic unit of charge (emu of charge) is the basic physical unit of electric charge in the cgs-emu system of units. One abcoulomb is equal to ten coulombs. CGS-emu (or "electromagnetic cgs") units are one of several systems of electromagnetic units within the centimetre gram second system of units; others include CGS-esu, Gaussian units, and Lorentz–Heaviside units. In these other systems, the abcoulomb is not used; CGS-esu and Gaussian units use the statcoulomb is instead, while the Lorentz-Heaviside unit of charge has no specific name.

  • 絕對庫侖(abC或aC)也稱為EMU電荷單位(emu of charge),是厘米-克-秒制的電磁單位制下的電荷單位,一絕對庫侖等於10庫侖。 CGS電磁單位制是厘米-克-秒制下的幾種單位制之一,其他厘米-克-秒制下的單位制有CGS靜電單位制及高斯單位制,這些單位制中的電荷單位是靜庫侖,不是絕對庫侖。 在CGS電磁單位制中,電流是安培定律定義的基本單位,而磁导率為一無因次量,在真空中的數值為1。因此此系統中一些方程式會出現光速的平方。 絕對庫侖的定義是由絕對安培(abA或aA)而來:假定二條分別載有一絕對安培的導線,距離一公分,其作用力為每公分2達因。而一絕對庫侖就是在電流為絕對安培時,1秒流過的電荷。 這是與度量衡、時間與曆法相關的小作品。你可以通过編輯或修訂擴充其內容。

  • The abcoulomb (abC or aC) or electromagnetic unit of charge (emu of charge) is the basic physical unit of electric charge in the cgs-emu system of units. One abcoulomb is equal to ten coulombs. CGS-emu (or "electromagnetic cgs") units are one of several systems of electromagnetic units within the centimetre gram second system of units; others include CGS-esu, Gaussian units, and Lorentz–Heaviside units. In these other systems, the abcoulomb is not used; CGS-esu and Gaussian units use the statcoulomb is instead, while the Lorentz-Heaviside unit of charge has no specific name. In the electromagnetic cgs system, electric current is a fundamental quantity defined via Ampère's law and takes the permeability as a dimensionless quantity (relative permeability) whose value in a vacuum is unity. As a consequence, the square of the speed of light appears explicitly in some of the equations interrelating quantities in this system. The definition of the abcoulomb follows from that of the abampere: given two parallel currents of one abampere separated by one centimetre, the force per distance of wire is 2 dyn/cm. The abcoulomb is the charge flowing in 1 second given a current of 1 abampere.
