A separately-excited DC generator, running at rated speed, has 6 volts across its armature terminals with no field current.
When field winding is excited with one ampere, the voltage builds up to 250 V at no load.
In case field current is reduced to zero, with the speed remaining unaltered, the armature terminal voltage would be
A. 6 V
B. less than 6 V
C. more than 6 V
D. zero
