It depends upon the condition.
But basically, to be a vector, the physical quantities needs to follow vector algebra.but current dos not follow it so it is scalar quantity.

Why is electric current a scalar quantity?
For a physical quantity to be termed a vector quantity, having magnitude and direction is not enough. The quantity should obey the laws of vector addition too. Like the triangle law or the parallelogram law. As we know, if two currents meet at a junction, the total current of the resultant current will be the algebraic sum of the two current and not the vector sum.Sometimes, treating a current like a vector makes sense, like when the current though a conductor induces a magnetic field.
What is the difference between vector and scalar quantities?
Vector quantity is a quantity characterized by magnitude and direction.Whereas,Scalar quantity is a quantity that does not depend on direction.
Is a force of friction a vector or scaler quantity?
Either, or both. Motion can be described in either vector or scalar terms. Speed is a scalar quantity, having only a magnitude. Velocity is a vector quantity, having both magnitude and direction. Acceleration is a vector quantity.
Name scalar fields and vector fields?
name as many scalar fields and vector fields as u can?
Voltage is a vector quantity or scaler quantity?
Scaler. Its vector counterpart is the electric field.
Is AC a vector or scalar quantity?
current is vector or scalar
Is electric current scaler or vector quantity?
Electric current is a scalar.
Is Moment Arm a scalar or vector quantity?
vector
Is the distance a vector or scalar quantity?
scalar direction is a vector quantity
A vector quantity has direction a scalar quantity does not true or false?
True, a vector quantity has direction, and a scalar quantity does not.
The main difference between a scalar and a vector quantity is?
A vector quantity includes a direction; a scalar does not.A vector quantity includes a direction; a scalar does not.A vector quantity includes a direction; a scalar does not.A vector quantity includes a direction; a scalar does not.
Is current a vector or a scalar?
Definitely current is a SCALAR. Current density, of course, is a vector quantity Current = charge / time Both charge and time are scalars Current density = current / area Here area is a vector quantity Hence scalar product of current density and area give scalar quantity i.e. current. So electric current is a scalar Of course we assign +ve and -ve sign to currents. It is not because of direction as we do incase of vectors. But it is only algebraic sign.
Which are the scalar quantities?
A scalar quantity is a non-vector quantity. In a vector quantity, direction is relevant. In a scalar quantity, it is not. For example, mass (measured in kg.) is a scalar; force is usually indicated as a vector (magnitude in Newton, but the direction is also relevant).A scalar quantity is a non-vector quantity. In a vector quantity, direction is relevant. In a scalar quantity, it is not.

Is pressure scalar or vector quantity?
Scalar quantity.
Is volume a vector or scalar?
Density is a scalar quantity. We don't talk about the density of a material as having direction, which is a characteristic of a vector quantity.
Is scalar quantiy is added with vector quantity?
A scalar quantity added to a vector quantity is a complex quantity. An example is a complex number z = a + ib, a is the scalar and ib is the vector quantity.If the vector quantity is 3 dimensional, ib + jc + kd, then the scalar and vector forms a quaternion quantity.
What is scalar vector?
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
