One of the mysteries of the English language finally explained.
The SI unit of electric charge, equal to the quantity of electricity conveyed in one second by a current of one ampere.
- ‘The charge of an electron is negative 1.6 times 10 to the negative 19 coulombs.’
- ‘Fifteen chloride ions were added to neutralize the system by replacing water molecules at the positions of lowest coulomb potential.’
- ‘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.’
- ‘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.’
- ‘One faraday of electricity is equal to one mole of electrons, which is equal to 96,487 coulombs of electricity.’
Late 19th century: named after Charles-Augustin de Coulomb (1736–1806), French military engineer.
