depends which component rheostat..if field rheostat is
there it should be at the minimum....the armature rheostat
should be at the maximum..it should be done to limit the
speed of the machine.....at starting due to very less
induced emf the speed increases terribly

i have flexible wire. size of conductors is 0.190 mm & no.of conductors are 48. then size of wire comes 1.37 sqmm instead of 1.5 sqmm . the what is tolerance for this size.
