current has a definite magnitude n we can specify a direction of its flow.but why its a scalar quantity?

Answer 1

Charge is a scalar. Current density is very definitely a vector field, and I would say that current can be thought of as a vector, too.

In circuit problems, since everything is in one dimension, the direction of the current can be expressed with a + or a - sign meaning "clockwise" or "counterclockwise."

Answer 2

its a scalar quantity since even though we can point its direction, its velocity alone can be consider as vector... durrent is not a quwntity unless u have your unit... if u say velocity of the current then it can be considered as vector... the velocity of the current not the current itself since the quantity is the velocity not the current... coz by defintioin,current is just a noun... but not the quantity unless there is an amount.

Answer 3

Current is defined as the rate of flow of charges.

I = Q/t. Neither Q nor time t is a vector.

Therefore I is a scalar.

Plus or minus is not a vector.

Generally we say that the current is flowing through a conductor.
But it is not correct. One must say that there is a current or charges flow through the conductor.

Current means rate of flow of charges; current flows will mean ‘rate of flow of charges flows” which is meaning less.

Thus current is a scalar.

The velocity of charges ( not current) is a vector quantity.

Answer 4

In Maxwell's Equations, current density J is a vector.
