Answer / kumar

actually input supply is AC .the return path is provided in
track by using rectifier Ac converted into DC & its fed to
Input supply of DC series motor so electric train is run
by dc series motor .

Answer / kiran

From over head transmission line,power taken by pantograph
is fed to rectifier which converts ac to dc and given to dc
series motor.the return path is provided through rails
which is connected to ground by insulating
equipment................

Answer / sandeep maheshwari @

The input supply is 25kv AC through the Pentograph.but the
electric train is run by dc current. so the ac current is
change into DC current by the use of RECTIFIER..& ITS FEED
TO dc SERIES motor.so ELECTRIC TRAIN IS RUN.....

Answer / percy

train gets supply from 25kv line through the pinto above
with this dc is genterated which is supplied to dc series
motor
and the is wheels to tracks and finally to ground

Answer / pyare

When electric train wire become down on ground than volt in wire 25kv than current voltage value

Answer / thowsrf_emerosn

Electric Train Supply or ETS is the supply of electricity
which powers electrical equipment on a train. It is usually
provided by the locomotive, and used to power auxiliary
systems on the rolling stock, usually coaches.
Originally, trains hauled by a steam locomotive would be
provided with a supply of steam for heating the carriages.
When diesel locomotives replaced steam, the steam heating
was supplied by a boiler - either oil-fired, or heated by
an electric element in the case of diesel-electric
locomotives. At this time lighting was powered by batteries
which were charged by a dynamo when the train was in
motion, and buffet cars would use bottled gas for cooking
and water heating.

Answer / pawan singh chauhan

25KV DC electricity gets electric train for DC SERIES
MOTORS .its current path same as by feed

It is a three inch fan and i want it to rotate to other direction .I've tried cutting the wire and reconnecting them inverse like black to white and white to black ,but it won't start rotating when i plug it in that way.And then it works again when i rejoin the wire to the way it is. I don't know what causing the problem.Is there anyone familiar with these small mortor?Any suggestion would be appreciated.Thanks!! http://i296.photobucket.com/albums/mm163/sasukebloodwheel/110527-105859.jpg

i work as a technician at a private company.. i used to take amp reading for certain appliances such as air con.. the problem is when i clamp the neutral, wire there is a current reading.. from my understanding for single phase system neutral should not have current unless if the circuit is not complete.. yet the air con still work
