| When testing the rotor of a synchronous motor for short circuits, a low voltage source is applied across the rotor coils through the collector rings. What would be the indication of a short- circuited coil? |
| A) high voltage drop reading, while the other coil readings will have an equal or lower value |
| B) low or zero voltage drop reading, while the other coils will have higher readings |
| C) steady voltmeter reading, while the other coil readings are fluctuating |
| D) fluctuating voltmeter reading, while the other coil readings are steady |
