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.

Is torque is a scalar or a vector quantity?
Since torque is a force, and as such has a direction, it is a vector.
What is Vector quantity?
Associates the direction taken with the speedAny quantity that has direction and magnitude associated with it is considered a vector quantity. An example of a vector quantity would be velocity. It must be expressed with reference to a direction.-aerol_
Is length a scalar or vector?
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
Is hours a vector or scalar quantity?
Since you can represent that with a single number, it isn't a vector - just a scalar.
Why current density is a vector quantity when current is scalar quantity?
Current density is a vector quantity because it has both magnitude and direction. It represents the flow of electric charge per unit area in a specific direction, as opposed to current which is the total amount of charge flowing through a conductor. The direction of current density indicates the direction in which the charges are moving.
Is density a vector quantity?
No, density is not a vector quantity. It is a scalar quantity that represents the mass of a substance per unit volume.
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.
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 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 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).
Why is current a vector?
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.
Is Electric displacement density scalar quantity?
no, it's a vector dude
Current is vector or scalar?
the current has a magnetude and phase angle or a phasor which in polar form
Why current density is denoted by J?
Current density is denoted by J to indicate the amount of current flowing through a unit area in a given material. It is a vector quantity, representing the direction and magnitude of current flow in a specific direction. The letter J is commonly used as a symbol for current density in physics and engineering equations.
Is electric potential difference a vector?
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.
Is magnetic field a scalar or density quantity?
A magnetic field is neither: it is a vector field with both direction and quantity.
