Which statement best describes the differences between single-phase and three-phase motors in terms of performance and applications?

• A. Three-phase motors provide smoother torque and greater efficiency for larger loads; single-phase motors are simpler, cheaper for small loads, typically less efficient and with lower starting torque.
• B. Single-phase motors provide smoother torque for large loads.
• C. Three-phase motors are smaller and less reliable.
• D. Single-phase motors require three-phase power to start.

Answer: (B)
