Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
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.’
- ‘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.’
- ‘One faraday of electricity is equal to one mole of electrons, which is equal to 96,487 coulombs of electricity.’
- ‘Fifteen chloride ions were added to neutralize the system by replacing water molecules at the positions of lowest coulomb potential.’
Late 19th century: named after Charles-Augustin de Coulomb (1736–1806), French military engineer.
