train uses acpower as its source.as in case of dc there would be only steady state conditions and transmission distance would be low.but in ac,it is sinusoidal waveform and transmission of power source can be done at a larger rate with high effeciency and minimal lose.so ac source is used in electric trains.

Why used ac over dc in train?
ac transmits the voltage over long distances. so v use ac in trains
What kind of current used in train?
Trains use DC currents! It's predominantly AC now but more dc in the early days. Both still in use. See DC and AC section below article-
What does ac stand for the mains voltage supplied in the UK?
AC stands for Alternating Current and DC stands for Direct Current.
Can friction produced by wheels of moving train generate electricity?
yes we can produce electricity by fixing dynamo in traction wheels so heat is produced when the friction of train wheel & track so the dynamo generates an power D.C SUPPLY and is converts into Ac supply so we can use that energy for electric trains use of lights and fans....
Why is AC meggering not used?
You do not use AC to megger a device, because the purpose of meggering is to measure the insulation resistance of the device. You use DC to do that. If you used AC, you would be unable to differentiate between insulation leakage and capacitance.
What are 3 devices that use AC elecricity?
Locate 3 devices that use AC electricity.
Why used ac over dc in train?

Train runs in DC or ac?
trains can run on both ac and dc. In India trains run with dc and there is a plan to convert them to move on ac by 2010

Is home electricity in the UK ac?
no ! ................
Can you use a marxs trains with a Lionel transformer?
Yes, Marx trains and Lionel transformers are generally compatible since they both operate on similar AC power systems. However, it's advisable to check the voltage and wattage ratings to ensure that the transformer provides appropriate power for the Marx trains without causing damage. Additionally, using a transformer with variable voltage control can help regulate the speed and performance of the Marx trains.
How many volts do the transperth trains use?
Transperth EMU (Electric Multiple Unit) Traction voltage is at 25KV AC, The current that runs though the train is quite the mystery tho :PHope this answer wasn't too late for you :)
What does ac stand for the mains voltage supplied in the UK?
AC stands for Alternating Current and DC stands for Direct Current.
How is ac supplied all over the UK?
By electricity pylons and cables
Does Australia use ac or dc?
240v ac
Do phones use ac or dc?
Some devices operate on AC and others on DC. Generally, anything that uses mains electricity (120V US, 240V UK) is using AC electricity and things that use batteries or are rechargable like cell phones, ipods, personal CD, use DC electricity.
Is my home 240 v ac?
The household supply in the UK is 240 V and is AC (alternate current).
