Why electric current is considered as scalar quantity still it require direction ?

Every quantity having direction need not be a vector. because if a physical quantity is to be regarded a vector, it has to satisfy certain conditions like
i) it should be added by parallelogram law

ii) it should be resolvable into components

iii) its addition should follow commutative law etc.,
 

 

In the case of electric current, its addition doesn't follow the parallelogram law, though it has a direction. hence it is a scalar but not a vector.
