Ampere (A) is named after the French physicist André Marie Ampère (1775-1836). According to the International System of Units (SI), the ampere is the unit of electrical current

.br> An ampere is defined as the current that produces a force of 2exp-7 Newtons per linear meter between two parallel wires of infinite length located one meter apart in

free space. Another definition of the international system of units specifies that 1 coulomb per second

isequal to 0.999835 amperes.

The ampere (A) is prefixed as kilo-amps (kA), which is equal to 10exp3, milli-amps (mA), 10exp-3, micro-amps (µA), 10exp-6, nano-amps (nA), 10exp-9, and pico-amps (pA), 10exp-12.
