单词 coulomb
释义

Definition of coulomb in English:

coulomb

(also C)
nounˈkuːlɒm
Physics
  • The SI unit of electric charge, equal to the quantity of electricity conveyed in one second by a current of one ampere.

    〔物理〕库仑

    Example sentencesExamples
    • One faraday of electricity is equal to one mole of electrons, which is equal to 96,487 coulombs of electricity.
    • The charge of an electron is negative 1.6 times 10 to the negative 19 coulombs.
    • Although this is not as accurate as a full treatment of the coulomb forces using a lattice - sum method, it is much cheaper and has been tested with the forcefield and algorithms used in these simulations.
    • The most dramatic is cloud-to-ground, often seen as forked lightning, which accounts for about 20 per cent of discharges and typically transfers tens of coulombs of negative charge from the cloud.
    • Fifteen chloride ions were added to neutralize the system by replacing water molecules at the positions of lowest coulomb potential.

Origin

Late 19th century: named after Charles-Augustin de Coulomb (1736–1806), French military engineer.
