Where does the power come form in an electric car?
The electricity comes from the batteries. The electricity then is converted into mechanical energy from the motor which is then put through the drive train to power the wheels.
How do you build a train with electricy?
Trains are built with plastic and metal. Electricity is used to run the motor in the train. The train gets the electricity from the track or catenary wire which is connected to the appropriate power supply.
Is an alternator part of power train?
No, an alternator is not part of the power train. It is an auxiliary to provide electricity.
How much electricity does a train need everyday?
Trains don't use electricity it uses coal trams use however electricity.
Why don't train wires sag when electricity flows through them?
because electricity has no mass and therefore no weight. electricity is not a physical object
Why is sulphuric acid transported by tankers and not by train?
train contain to much static electricity due to its metallic body but trucks a truck discharges the static electricity to the earth, so if sulphuric acid is transported by train that would cause an explosion due the reaction of sulphuric acid and static electricity
What is the most eco-friendly train?
The most eco - friendly train is the one that do not contribute pollution to the environment. A train runs by electricity is one.
Do maglev trains use renewable energy?
Depends. maglev trains run in electricity, and electricity can come from all sorts of sources. You can get it from hydro Power, nuclear Power, fossil fuels, solar Power etc. Renewable or not doesn't matter to a maglev train. They can run on anything that can be turned into electricity.
Which fuel is used for running metro train?
Usually electricity.
Why is it impossible to generate electricity with a moving train through its moving wheels?
It is not impossible. This is called "regenerative braking". By turning the motor into a generator (switch round the wiring) the train is slowed down and (if it is an electric train) the electricity produced can be put back into the electrification system for use by another train that is accelerating at the same time. But when you do this you slow the train down, so it makes no sense except when you want to slow it down. Otherwise you are just turning electricity into movement and turning it straight back into electricity, and very inefficiently.
What are the three thangs transfered by conduction?
* heat, * electricity, * passengers on a train
When did electricity come to Nevada?
It gets the power from the electricity lines.
