Term of the day : 'Ampere (A)'
The unit of current. 1 Ampere is equal to a flow of one coulomb of charge per second. SI definition is the current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 metre apart in a vacuum, would produce a force equal to 2 x 10-7 newtons per metre of length. Written as 'ampere' or 'amp'. By Ohm's Law, a current of 1 amp through a resistance of 1 ohm will cause a potential difference of 1 volt.
