Find the time domain equation corresponding to each phasor: a) V = 18.6 (-54 degree) V b) V = (20 + j80 - 30(15 degree) V
Find the time domain equation corresponding to each phasor:
a) V = 18.6 (-54 degree) V
b) V = (20 + j80 - 30(15 degree) V
In-circuit analysis, a phasor is a complex number in polar form. A phase vector, also known as a phasor, is created by plotting the amplitude and phase shift of a sinusoid in a complex plane.
A phasor can be thought of as a revolving vector. A phasor has magnitude VA and angular displacement, unlike a vector, which has both magnitude and direction. From the positive x-axis, you measure angular displacement in the counterclockwise direction.
A voltage phasor is depicted as a revolving vector at a given frequency, with its tail at the origin. If you need to add or subtract phasors, you can use trigonometry to split the vector into its x- and y-components.
