Type
Description

"Voltage Phasor" is a representation of voltage as a sinusoidal integral quantity using a complex quantity whose argument is equal to the initial phase and whose modulus is equal to the root-mean-square value. A phasor is a constant complex number, usually expressed in exponential form, representing the complex amplitude (magnitude and phase) of a sinusoidal function of time. Phasors are used by electrical engineers to simplify computations involving sinusoids, where they can often reduce a differential equation problem to an algebraic one.

When $$u = \hat{U} \cos{(\omega t + \alpha)}$$, where $$u$$ is the voltage, $$\omega$$ is angular frequency, $$t$$ is time, and $$\alpha$$ is initial phase, then $$\underline{U} = Ue^{ja}$$.
