Yes, dynamic braking uses a dynamo to save energy when the train slows down. Normal brakes, using brake shoes on the wheels, get hot and waste the train's kinetic energy to the air. Instead, a dynamo produces a braking effect and at the same time sends the energy either into a battery or back into the train's overhead supply.
An electrically driven train's driving motor can be used instead of a separate dynamo.
What else can I help you with?
What will happen if you use less electricity?
you will save money
How do you encourage other people to use less electricity?
I suggest you tell them for every electricty dollar they save you will give them $10.
How much electricity do plugged-in appliances use?
The amount of electricity used by plugged-in appliances varies depending on the appliance and how long it is used. Appliances like refrigerators and air conditioners use more electricity than smaller devices like lamps or phone chargers. It is important to unplug appliances when not in use to save energy.
Is electricity saved?
we can save/store electricity in batteries but economically we can't save electricity in pump storage plant we used to store the water back in the dam at night time during low power demand which we can use during day time (high power demand). so its a type of storage of electricity in form of water head in dam.
Can a 9 volt motor rotate 9 volt dynamo?
Are you going to use the 9-volt motor as a dynamo, and the 9-volt dynamo as a motor? Yes, the motor can rotate the dynamo because DC motors and DC generators are actually the same thing--they just apply power to the terminals of a motor to make it turn, and turn the shaft of a generator to make power appear at the terminals. Having said that, if you're going to try to connect the shaft of a 9v motor to the shaft of a 9v dynamo, and use the dynamo to power the motor so as to create a perpetual motion machine...that won't work. The motor wastes a little bit of energy, as does the dynamo. It is possible to build a device that uses a motor to drive an alternator, which is the AC version of a dynamo. You power the motor from the AC grid, and power something that's very sensitive to noise on the line from the alternator. This is called a Motor Generator set, and it's how they powered Cray-1 supercomputers.
Can we use dynamo in train's wheel?
i think if we use dynamo in bicycle for lightning purpose so trains wheel is also similar to that of bicycles wheel. actually i wants to save electricity which ios given to the train for lightning and fans
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....
How do you converting heat into electricity?
Use the heat to boil pressurized water. Use the pressurized steam created to spin a turbine connected to a dynamo. The dynamo then produces electricity.
Is dynamo evil?
No, Dynamo is not inherently evil. It is a tool or device that generates electricity using electromagnetic induction. Its use and intention can vary depending on the context and how it is utilized.
How can one use windmills for electricity?
The use of wind power for electricity involves the attachment directly or indirectly of a magnet to the turbine to spin within a dynamo to generate a current.
How did the dynamo improve lives?
Dynamo improved lives alot eg. hospitals get electricity from a power station which uses dynamo to create it if we hadnt discovered dynamo there would be the hospital system today as such for a lot of things. TV, computers, anything electrical . Of course you could use solar panels to creatre electricity but you would need huge solar panels which are very expensive to power up the world.
How much electricity does a train need everyday?
Trains don't use electricity it uses coal trams use however electricity.
What types of electricity saver ideas are available?
There are many ways to save electricity. One way to save electricity is to be mindful of one's surroundings, meaning turn lights of when leaving a room or turning off items that are not in use. Another way to save electricity is to use items that use less electricity or have the energy star logo on it.
What will happen if you use less electricity?
you will save money
Why do you save electricity?
In this context, to save electricity is "not to use it" rather than to "save it somewhere safe". The primary reason for consumers is that by not using electricity, you will not have to pay for it. The secondary reason is that if we, as consumers, use less electricity then the suppliers will not have to produce so much either which, in turn, means that less greenhouse gases will be produced at electricity generating stations.

You turn off the things that use it
