Question

A phase angle in the frequency domain corresponds to

a. the initial slope of the sinusoidal signal.

b. the angle at which measurements should be taken for the most accurate results.

c. a delay or advance in time as compared to a pure cosine wave.

d. the angle of the approach vector of the voltage.

Answer 1

c. a delay or advance in time as compared to a pure cosine wave.

Step-by-step explanation:

Electrical phase is measured in degrees, with 360° corresponding to a complete cycle. A sinusoidal voltage is proportional to the cosine or sine of the phase. Phase difference , also called phase angle , in degrees is conventionally defined as a number greater than -180, and less than or equal to +180.

The phase angle corresponds to delay or advance in time as compared to a pure cosine wave.
