Negative phase angles in polar plots are measured:

• A. Clockwise
• B. Along real axis
• C. Counter-Clockwise
• D. On imaginary axis

Answer: (A)

Negative phase angles in polar plots are indeed measured clockwise. In a polar plot, angles are typically represented with respect to the positive real axis, where a positive angle is measured counter-clockwise. Conversely, when dealing with negative phase angles, the convention is to measure these angles in the opposite direction. Therefore, a negative phase angle results in a clockwise measurement from the positive real axis, making this the accurate description of how negative angles are indicated in polar plots. Understanding this directionality is critical in various applications, including signal processing and control systems, where phase relationships are important for system behavior analysis.
