Define current. Give its $SI$ unit.
(N/A) Electric current is defined as the rate of flow of electric charge through a conductor. Mathematically,it is the amount of charge $Q$ flowing through a cross-section of a conductor in time $t$,expressed as $I = Q/t$.
The $SI$ unit of electric current is the ampere $(A)$,which is equivalent to one coulomb per second $(1 \ A = 1 \ C/s).$
