The described generators are three-phase (3Ø).

The described generators are three-phase (3Ø).

• A. Single-phase
• B. Three-phase
• C. Four-phase
• D. DC

Answer: (B)

Three-phase generation means the generator produces three sinusoidal voltages that reach their peaks at intervals of 120 degrees. This arrangement gives smoother, nearly constant power delivery and lets power systems run motors more efficiently with less voltage ripple and simpler transformers and conductors. If the description specifies three-phase (3Ø), the correct identification is three-phase, not single-phase, DC, or an uncommon four-phase term. Single-phase would have one sine wave and more pulsating power; DC is unchanging; four-phase isn’t a standard designation for typical IEC generators.
