Question

Is current a vector quantity? state your answer with suitable example

Answer 1

THe direction should really be considered to be "sign" more than a proper vector direction. In particular, Current is defined by defining a surface, and then counting the number of particles that cross that surface per unit time. It only depends on the relative orientation of the surface and the charges, it has no absolute notion of distance. More mathematically, the vector nature of these things is dotted out: I=∫j⃗ ⋅dA⃗

Answer 2

Current is not a vector quantity. Current in circuit is added by just giving positive to one direction and negative to opposite direction (Kirchhoff's law).
