Question: To connect a single-phase 120V motor that can also run on 240V, you would typically:
Answer options: ✅ Connect the windings in series for 240V and in parallel for 120V.
- Connect the windings in parallel for 240V and in series for 120V.
- Use a step-up transformer for 120V operation.
- Replace the motor's starting switch.
Correct answer: Connect the windings in series for 240V and in parallel for 120V.
Explanation: Dual-voltage single-phase motors have two separate run windings. For the higher voltage (240V), the windings are connected in series, so each receives 120V. For the lower voltage (120V), they are connected in parallel, so each still receives 120V.
