Current is not scalar. Current is a vector quantity. For simplicity, in electric circuits, current is scalar because the direction is assumed to be one way or another, rather than three dimensional.
Electrical current is the amount of charge passing through a given area per second (dQ/dt). As only the movement perpendicular to the area is important, there are only two possible directions (+ or -)
A vector has both magnitude and direction..Current density has a flow of direction because it has velocity,so current density is a vector quantity..
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.

vector quantity
Length is a scalar quantity. By definition, a vector quantity has both magnitude (ie. length) and direction. Length does not have direction, so it is not a vector. Length is a scalar quantity. Length is a scalar quantity. yes
scalar quantity has only magnitude whereas vector quantity has magnitude as well as direction
Since you can represent that with a single number, it isn't a vector - just 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.
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.
current is vector or scalar
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.
Electric current is a scalar.
Current Density describe how charge flow at certain point since current density = I/A and the vector direction tells you about the direction of flow at that point.
no, it's a vector dude
the current has a magnetude and phase angle or a phasor which in polar form
We generally think of electric current as a scalar quantity. When we think of 1/4th amp or 20 amps, we think of an amount (a scalar quantity) of current flow. On another plane, the electromagnetic forces at work in current generation are actually force vectors. In the traditional sense, electric current, which is the movement of electrons, is from negative to positive. This is not a vector, though. In the macro or "large" world, think of current as scalar.---------------------------------------------------------------------The beauty is that though current is not a vector definitely its direction of flow is used to make length as vector. I is not vector. dl is not vector but I dl will be considered as vector. So innovative and essential concept.Current density is a vector which appears in Maxwell's equations.
A magnetic field is neither: it is a vector field with both direction and quantity.
Which of the following is a vector quantity
True, a vector quantity has direction, and a scalar quantity does not.
