Question

Is current is a vector quantity or scalar quantity?

Answer 1

there are two conditions for a quantity to be a vector:
1) it has to have magnitude and direction
2) it has to obey the laws of vector addition
Now current satisfies the first but fails the second
therefore it is a scalar quantity

Answer 2

@rajathsbhat, And If I thinks in terms in electron transfering energy from one place to other either, it is AC or DC then, it seems that its a vector quantity...

Answer 3

current is a scalar quantity from definition I=dq/dt, while current density is a vector j=dq/dt*dS, taking direction of the normal to the plane dS

Answer 4

Current is a tensor quantity, i.e., its direction is known...

Answer 5

It is incorrect to say that it is a scalar..
Basically there are three types of physical quantities- Scalars, Vectors and Tensors..
Scalars are those which have magnitude but no direction.
Vectors are those which have magnitude as well as direction and which follows vector algebra...
Tensors are those which have magnitude and also direction but their direction is known...

Answer 6

Sidharthsahoo, I'll check about tensor quantity then I'll come to you
