What does the term phase relate to?

• A. The relationship of one sine wave to another in terms of time delay
• B. The relationship of one sine wave to another in terms of electrical degrees
• C. The amplitude difference between two sine waves
• D. The frequency difference between two sine waves

Answer: (B)

Phase describes how far one sine wave is shifted relative to another within a cycle, and it’s measured in electrical degrees. This tells you whether the waves line up or one leads or lags the other, with 0° meaning they peak together, and 90° or 180° indicating quarter- or half-cycle differences. It’s about the timing relationship between waves, not their height (amplitude) or how fast they repeat (frequency). A time delay can produce a phase shift, but in practice we express that shift in degrees for AC analysis.
