∙ 10y agoThe difference between AC Trains and DC Trains is the voltage supplied. The DC is only really viable up to 1500 V.

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-
Why is AC used?
The power source is AC. Hence AC is used. DC application is limited.
Where would DC be used instead of AC?
DC is used for extra-high voltage transmission systems, as there are less losses with DC than with AC, and no synchronising problems.
Does the galvanometer measures AC and DC current?
It is used to detect very small DC currents only. For AC signals Detectors are used.
Will value of J be same if ac were used instead of dc?
The number of Joules (energy) is the same as dc provided the RMS values of the ac quantities are used.
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
What kind of current used in train?

Is the metro rail train using ac or dc power supply?
dc power supply
Is commutator used for both ac to dc and dc to ac conversion?
Yes
What is a DC AC inverter used for?
A DC/AC power inverter is used to convert DC, the power that comes from a car's battery, into AC, the kind of power that is supplied to a home and used to power larger electronics.
Which diode are usd are rectifying ac into DC?
Junction diodes are used for rectifying ac into dc.
How do you change over a ac motor to a dc generator?
Type your answer here... how can you change an ac motor to a dc generator
Why is AC used?
The power source is AC. Hence AC is used. DC application is limited.
How do you build a dc to dc converter?
A DC to DC converter is basically a type of switching power supply. The switcher converts the input DC to AC. A transformer is used to convert the AC to the desired voltage. A rectifier, filter, and optional regulator is used to convert the AC back to DC.
Where would DC be used instead of AC?
DC is used for extra-high voltage transmission systems, as there are less losses with DC than with AC, and no synchronising problems.
What devices can be used to block DC and pass AC?
simple capacitor can do this job (to block dc and pass ac).
Is DC or AC used to light a light bulb in the home?
AC...
