Why machine give shock
A separately excited dc motor having 2 ohm armature resistsance draws a current of 10A and torque developed is 20 Nm under rated field condtion. the speed of the motor under the rated field condtion , when it is connected to a 100V DC source and delivering 10Nm torque....
why neutral and earth should not be connected on 3 phase 440v/50c/s supply at consumer side. where as on 25kv/ac/50c/s railway traction substation neutral and earth will be connected and track at substation. and track will act as neutral and earth. Reasons for this is needed urgently
