As shown in the illustrated diagnostic setup for locating an open field coil of a tenpole synchronous motor, if 240 VDC is applied across the brushes, what statement is true if one of the field coils is open-circuited? Illustration EL-0203
A
The voltage across the collector ring and any point before the open will be line voltage and the voltage across the collector ring and any point after the open will be zero voltage.
B
The voltage across the collector ring and any point before or after the open will be line voltage.
C
The voltage across the collector ring and any point before the open will be zero voltage and the voltage across the collector ring and any point after the open will be line voltage.
D
