Is AC voltage scalar or vector?

The answer is, AC voltage and current are described by phasors. They have both an amplitude and a phase so a single scalar quantity is not sufficient to describe them.

Is voltage a scalar or vector quantity?

scalar quantity
Voltage is a scalar quantity and can be calculated by the product of current (scalar) and resistance (scalar). Work is a vector quantity and can be calculated by the product of a force (vector) and displacement (vector).

Is phasor a vector or scalar?

Phasors are complex numbers. They are scalars, although we can also define them in terms of magnitude and angle on the complex plane. Vectors are vectors.

Are phasors vector?

A phasor is a rotating vector. Whereas a vector represents quantity and direction, a phasor represents quantity and displacement measured in a counterclockwise direction. Phasors are used in electrical engineering to represent certain AC quantities -e.g. the relationship between current and voltage.

Is AC current vector quantity?

Electric current is a scalar quantity. Any physical quantity is termed as a vector quantity when the quantity has magnitude and direction.

Is alternating current is a vector quantity?

To be precise, current is not a vector quantity. Although current has a specific direction and magnitude, it does not obey the law of vector addition.

Is electric voltage a vector?

No, the voltage is not a vector. The voltage is the difference in the electric potential, wich is a scalar. Electric potential is a scalar obtained by the scalar multiplication of two vector quantities, electric field and the displacment vector.

Is electric capacity a vector?

Option A: Thermal capacity, Magnetic susceptibility and the Electric charge are the physical quantities which depend on the properties of matter and hence they are the scalar quantities. So, all the three sets of answers are not vectors.

What is voltage phasor?

A phasor is a complex number in polar form that you can apply to circuit analysis. When you plot the amplitude and phase shift of a sinusoid in a complex plane, you form a phase vector, or phasor. Here is a diagram of a voltage phasor as a rotating vector at some frequency, with its tail at the origin.

What are Phasors and voltages?

So we can say that a phasor represent a scaled voltage or current value of a rotating vector which is “frozen” at some point in time, ( t ) and in our example above, this is at an angle of 30o. For example, voltage and current.
