Multiple Choice

The power is connected to a single phase motor using __________ lines.

Explanation:
Single-phase power is delivered across a voltage difference between two conductors. A single-phase motor has its windings energized by that difference, so you only need two lines: one carries the supply potential and the other serves as the return. If more lines were used, it would indicate a polyphase (three- or four-wire) supply for motors designed to run on multiple phases to create a rotating magnetic field. Two lines are sufficient to energize a simple single-phase motor, making two lines the correct arrangement.
