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....
Because the electrical parts of a transformer do not move / rotate.
Dams: Falling water spins turbines to generate electricity.Wave power: Ocean waves transfer their energy to moving machinery which generates electricity.Tidal power: Tidal water rushes through narrow channels turning electricity generators.
No. While the proton has the opposite charge of the electron, the proton will not flow from atom to atom like the electron does because the strong atomic force holding the proton in the nucleus is much more powerful than the electromagnetic force.
The advantages of a moving iron ammeter is that it can accurate measure the amount of electricity which is flowing. This makes it well suited for both monitoring and controlling the amount of electricity in a circuit.

If a conveyor belt is moving it can generate static electricity by friction. It needs to be isolated from the Earth to do this.
You question is meaningless but the use of moving water to generate electricity is called 'Hydroelectricity'.
The friction produced that stops an object moving when force is applied is 'static friction'.
Turbines
Helicopters generate static electricity due to the friction between the rotor blades and the surrounding air. This friction causes a build-up of electric charge on the blades, which can discharge as a spark when the helicopter lands or when personnel come in contact with it. Grounding systems are used to prevent static electricity build-up on helicopters.
Hydropower is energy produced from water. It involves harnessing the energy from moving water, such as rivers or waterfalls, to generate electricity. This renewable energy source is clean and sustainable.
Hydropower does not use heat to generate electricity. Instead, it harnesses the energy from moving water, such as rivers or waterfalls, to generate power through turbines.
electricity from water is called hydro - or hydroelectric power
The turbine, to generate electricity.
Static electricity occurs when there is a buildup of electric charge on the surface of an object due to friction with another surface. This charge imbalance can cause sparks or shocks when the object comes into contact with a conductor or a grounded object. Static electricity is more likely to happen in dry environments or when certain materials, like plastics or rubber, are involved.
Hydropower.
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.
