In DC(direct current) circuits, voltage is scalar. But in the case of alternating-current(AC) voltage is vector quantity. It is because in an AC circuit the current is changing the direction for every time period. Therefore, since in this the direction matters its a vector quantity.

In DC circuits, where there is no frequency component, potential difference, measured in volts, is a signed scalar quantity. In AC circuits, there is a frequency component, the resistance of wires and other components can have a frequency-related component which causes voltage current to be out of phase to each other. In this case it is useful to represent potential difference and current as a vector, having a real and imaginary component. Components like capacitors and inductors that cause the voltage and current to get out of phase are called reactive.

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.

True, a vector quantity has direction, and a scalar quantity does not.

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.

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.
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.
