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.
AC is a vector quantity because it has both magnitude and direction. Velocity, force, and displacement are examples of vector quantities, and they can be represented by arrows in the appropriate direction.
Electric current is a scalar quantity as it only has magnitude (typically measured in amperes) and no direction.
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
Resistivity is a scalar quantity. It is a measure of how strongly a material opposes the flow of electric current through it.
When multiplying a vector by a scalar, each component of the vector is multiplied by the scalar. This operation changes the magnitude of the vector but not its direction. Similarly, dividing a vector by a scalar involves dividing each component of the vector by the 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.
scalar. although current has magnitude(1A,20A,5A etc) and direction but it does not follow vbector laws. hence it is a scalar quantity
A scalar times a vector is a vector.
the current has a magnetude and phase angle or a phasor which in polar form
vector

A vector quantity is one that has a magnitude (a number), and a direction. No, resistance is not a vector quantity; it is a scalar quantity (only magnitude).
