scaler...just for the fact that it denies the vector's law of addition .( next question of urs ::but hey ! it has direction and magnitude ..so y not its a vector? )

here is a proper answer :::

ITS A SCALAR .BUT IN CIRCUITS WE DEFINE THAT DIRECTION OF CURRENT IS DE DIRECTION OPP TO THE MOTION OF ELECTRONS.IT DOESNT MESN THAT ITS A VECTOR , IT REPRESENTS DE RATE OF FLOW OF CHARGES. WE KNOW THAT ELECTRIC CHARGE IS A SCALAR QUANTITY.ACCELERATION (RATE OF CHANGE OF VELOCITY )IS A VECTOR, BECAUSE VELOCITY IS A VECTOR.AND THE ANGULAR DISPLACEMENT THETA IS ALSO A SCALAR THOUGH IT HAS DIRECTION OF ANTICLOCKWISE

Tensors are those quantitites that have directional sense along with their magnitude, but do not obey any laws of vector algebra

examples : current, pressure, i think stress also

It is scalar ...because it doesn't follow vector rule...

Although current and pressure both display direction to the naked perception but they are not vectors because of this that ... Blah blah ... Everybody here are talking bout laws they don't follow ... Who said that they have to follow the laws ... I find everyone here studies and understand only on the basis of laws, definitions and formulas.... And not on the basis of understanding and realisation. I will tell you guys why these tensor quantities are not called vectors without using any law ... Here is goes ..For being a vector ur basic need is to have a well defined direction implicitly attached to u... Pressure generates a force but the direction of the force is generates depends on the alignment of the area on which this force is considered... Change the alignment and the force direction will change ... So pressure as a physical quantity does not have its own direction ... It can generate a force in any direction depending upon the area alignment.

Current direction actually depends on the alignment of the conductor between two points having a potential difference... U place the conductor in a different way ... Current directions will change .. So current instrinsically does not have its own unique direction...hence can't called be a vector....

For being a vector u should have a well defined instrinsic direction.
