    It can also be said that since current is the dot product of two vectors current density j and area S it is a vector since dot product gives a scalar quantity.

    The direction of current is only a convential direction we are using to solve problem in physics .Actually current doesn't have any direction as it doesn't obey vectors law of addition and parallelogram law of vactor . Suppose a current is flowing in a wire placed in a x axis then after resolving the component sin and cos it doesn't have any significance as the sum now obtained is different from the actual value of current .
