Current is nothing but, the flow of charges. So, current is not dependent on any other base unit. Current constitute charges invariably, you cannot consider charge as a seperate entity.
The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 metre apart in vacuum, would produce between these conductors a force equal to 2 × 10−7 newton per metre of length.
Hope this helps.
