|what is the function of Choke?
|Why the motor was take the starting current is high?
|why there is a fault occurs, if a phase wire touches ground..
and the fault not occurs when we connect a bulb between phase
|Can u explain : what is supply for train (whether a,c or d.c
).I know that supply is 25000v a.c .But there is rumour that
supply is D.C.
And also explain how lights and fans inside the trains are
working ,and what type of motors are used in trains whether
D.C motors or induction motors .If d.c motor, how it gets
supply.If traction motors are used then what are traction
motors and its functions and how it differs from other
motors and also explain about locomotive .
