A physical quantity like for eg electric current which has a definite direction in an electric circuit but does not obey the rules of vector addition,instead add up like scalars. like if current fro to branches of an electrical circuit is meeting at a junction and continues as a single total current then the total current is the scalar sum of currents form the individual branches.i(net)=i1+i2.

The term tensor has slightly different meanings in mathematics and physics. In the mathematical fields of multilinear algebra and differential geometry, a tensor is a multilinear function. In physics and engineering, the same term usually means what a mathematician would call a tensor field: an association of a different (mathematical) tensor with each point of a geometric space, varying continuously with position.
In classical mechanics, mass, temperature, and other scalar quantities are tensors of rank 0; but force, momentum and other vector-like quantities are tensors of rank 1. The novel aspects of tensor theory are seen from rank 2 onwards.
