Question

A 4-pole, separately-excited, wave wound dc machine with
negligible armature resistance is rated for 230 V and 5 kW at a
speed of 1200 rpm. If the same armature coils are reconnected to
form a lap winding, what is the rated voltage (in volts) and power
(in kW) respectively at 1200 rpm of the reconnected machine if the
field circuit is left unchanged?
(a) 230 and 5
(b) 115 and 5
(c) 115 and 2.5
(d) 230 and 2.5
