Current

it is scalar..

it has magnitude and direction but it does not follow the Triangle rule of vectors.

no it is calld as constraint vector.

till our level, it is a scaler and reason has been justified by ronald...but as our physics sir told us in 11th and now while teaching this too, current is a tensor...which is neither a scaler completely , and nor a vector...

but he told us that we need not know much about tensors now coz it is not a part of JEE syllabus, but M.Sc...

and so, for our level, it is a scaler...i hope i m clear...

yes ur rite.but it is not a scalar .This is due to the direction of flow is necessary for finding the magnetic field.That is y it is called as constraint vector which was given in one of the mtg issue.

As a whole it can be said dat it is a mixture of vector and scalar
