25,000 volts
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 :)
Many factors, such as size and power, affect the cost of an electric train set. In general, these sets cost anywhere from 60 dollars to nearly 300 dollars.
how many days taken to reach kerala from delhi
It depends on the voltage it runs on. The answer would be the wattage 15,000 divided by the voltage. Example at 240 volts it would run on 62.5 amps.
Need to know the voltage of the motor.
As many as you like but the total current taken is limited by the circuit breakers.
2800 watts at 240 volts would give you the 80 percent derated ampacity. <<>> Without a voltage voltage being stated, an answer can not be given. Electric heaters are sized by wattage and are used on many different voltages. Wattage is the product of amps times volts. So as you can see without the voltage the question can not be answered.
Four constraints should be taken in optimal placement of capacitor problem for voltage improvement using the Particle Swarm Optimization.
An electric heater is an electric appliance that convert electrical energy in to heat. Working principle of an electric heater as per "Joule heating theory" When electric current passes through a resistor that electric energy convert to heat (best and simple example is a spring type heating element). When Voltage applied both end of a wire/spring type Resistance wire, voltage flow and this voltage help that wire to heat up and convert in to heat. A Resistance wire quality, length & thickness depend how many time heat spread and resist with that heat. K.watt/ Watt = Applied voltage x Ampere. Many quality and types of electric heating elements are there depend upon purpose of use. Few best heating elements known as Kanthal wire, Nicrome wire, Ureka wire, Super Kanthal, Silicon Carbide heating elements etc.
To figure that out you need to know the Amperage that it draws and what the voltage of the circuit is that you're using. Once you know that you can figure out how many watts it uses by doing simple math. Voltage x Amperage = Watts
I have taken the train from Frankfurt to Berlin and it takes around 2.5 hours.
