Question

define s. i. unit of current

Answer 1

The SI unit of current is ampere. 1 ampere is the constantcurrent that will produce an attractive force of 2 × 10^−7 newton per metre of length between two straight, parallel conductors of infinite length and negligible circular cross section placed one metre apart in a vacuum.

Answer 2

S.I unit of current = Ampere (A)

When 1 coulomb (C) of charge flow through wire in 1 second (s) through any cross sectional.

1A=1C/1s
