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.

Is current a scalar or vector quantity?

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.


Is a current a vector or scalar?

scalar. although current has magnitude(1A,20A,5A etc) and direction but it does not follow vbector laws. hence it is a scalar quantity

Is AC a vector or scalar quantity?

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.


Is electric current scaler or vector quantity?

Electric current is a scalar quantity as it only has magnitude (typically measured in amperes) and no direction.


Can you add a scalar to a vector?

Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.


Is resistivity vector or scalar?

Resistivity is a scalar quantity. It is a measure of how strongly a material opposes the flow of electric current through it.


Is time a scalar or a vector?

Scalar


Multiplying or dividing vectors by scalars results in what?

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.


Is resistance a 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).
