BASE UNITS
Asked by isha007 | 12 May, 2010, 07:55: PM
Expert Answer

Dear student,

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.
