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
