whats the working principle of electric trains?(complete explanation)?

Question

technical explanation (how it runs using electric energy?)

Answer 1

The power coming from your wall is converted and used to create a slight voltage between the two tracks. The train, which is in contact with both tracks, uses this voltage to drive a simple electrical circuit onboard the train. Easy.

In case you don't know, voltage drives a current though a resistance. Voltage is difference in electrical "pressure" and can be induced by a power source or battery. Current is the movement of electrons in a metal. Resistance is a natural impedance to current, caused by the properties of the materials being used. Lights, motors, and other components also cause resistance.

Answer 2

The transformer reduces the electricity from 110 volts to a lower voltage. This voltage is fed to the rails. One side is positive the other negative. The train picks up the electricity through the wheels and takes it to an electric motor that turns the drive wheels with a set of gears. The voltage can be increased to go faster or reduced til the train stops.
If you want an explanation of how a transformer works or how an electric motor works post another question.

Answer 3

when some one hit on head not hard just to tease it means he loves you too much. Don't take him otherwise. Always give him nice look and pleasing words. He is your younger brother. Apprise him of this fact and tell him that he should respect his elder sis. Always take care of him so that he feel easy going and also have great reverence to you. He should be impressed of your care taking attitude. convince him that he is your good brother and he should obey his sister. Tell him "You know, how much I care for you". with you loving behavior you can bring change in his attitude toward you. Thank you.
