Define one unit of current

1.	Define one unit of current
Answer» SI unit of current\xa0is ampere. 1 ampere is the constant\xa0current\xa0that will produce an attractive force of 2 × 10−7\xa0Newton per meter of length between two straight, parallel conductors of infinite length and negligible circular cross section placed one meter apart in a vacuum.\xa0When 1 coulombs of charge flow through any cross-section of a conductor in 1 second, the electric current flowing through it is said to be 1 ampere.
