What is the problem with using an electric motor to run a generator stepped up with transformers that is used to run the motor and give electricity for other uses?

It's all to do with the conservation of energy. The output power of the transformer cannot be greater than the input power from the motor used to drive your generator! In fact, it will be significantly lower than the power of your first motor due to the efficiency of the motor, of the generator being driven by that motor, and of the transformer. So if you then try to run the original motor from the output of your transformer, the energy-losses will simply accumulate, and the motor will not be able to run!

Why are generators helpful?
Electrical generators produce electric power, and generators solve the problem of production. We use electricity in countless ways, and we need to access some kind of generator if we can't directly access the power grid.
What are the causes of failure of self excited generator?
there is problem in AVR and magnetic strength.
Can an oil fired furnace be run off a generator?
If you have an older one with a standing pilot light, one that is on all the time, you probably can. I've been told that the newer ones with electric ignition are a problem. They have electronic parts that don't like generators and will short out the circuit boards. This is from a Heating and Air guy so I tend to believe it.
What is the difference between a floating output signal generator and a grounded output signal generator?
A signal generator can be used to function in two ways. In high frequencies, one of output probes of any generator (negative probe) will be grounded automatically, hence it has to be connected with grounded parts of other elements not to create a short circuit problem. But, in the case of floating type (f<100 Hz, generally) probes of the signal generator is not grounded.
What problem occurs when a generator is run at 50 percent load?
After given 50% load that time engine was start to hunting

How can I get more power from my generator?
The best way to solve your problem would be to discuss options with your electricity supplier. They may be able to solve your problem sufficiently without very much hassle.
Does electricity continue to flow through a table lamp when the switch is on and the bulb is removed from the lamp?
Electricity flows by any conductor.But the most used to flow electricity is copper. Now if there is any problem with a wire even if it is a conductor the electricity will not flow.Sometimes when trying to make an electric circuit the electricity does not flow,if the wirehas no problem it is a problem with connection to make that work you just put silver paperbetween the 2 wires that have a problem in connecting to the bulb or any such thing.

What problems faced power stations to transmit electricity to the cities?
One major problem was how to transfer electricity over long distances, without loosing the current. The current may dissipate over a long circuit, so what you get at the city is only a fraction of what you generated at the plant. This problem was overcome by using large transformers. They convert high current/low voltage to a low current but very high voltage. The electricity is then carried across land with minimal losses and once nearer its destination will be converted back to a higher current/lower voltage through the use of further transformers.
Power factor in DC?
Power factor is defined only for alternative current. Power factor=1 (largest value) means the alternative voltage and current are in phase with each other. In this case, all the energy coming from the source (generator) is absorbed by the user (load). A power factor lower than one (in AC) means in a cycle of voltage, in a portion of time the energy is used by the load, but in the rest of the cycle, the energy is going back to the generator. The main problem with low power factor is LOSS of ENERGY in the wires during the time energy goes back to the generator. During this time the used does not pay for the electricity (and gets negative bill) , however the loss in electric is still there. Coming back to the main question, equivalent of this situation in DC, happens if the load (user of electricity) becomes generator. An example of this case is an alternators that becomes generator for sometime. Maybe be popularity of wind turbines and reselling back electricity to the grid, the tern "DC power factor" will be defined. Alain Izad, Ph.D.
What will cause a humming noise in radio?
It can be interferance caused by Fluorescent lights, Transformers, (such as battery chargers) switchless lights, you name it. Anything that plugs into electric current in your home can in one form or another. In your quest to find the problem, you will often overlook what the actual problem is.
How do electric cars save the environment?
They do not. Indeed by using electricity from power stations they save about third of emmisions. On the other hand, enormous environmental problem is created by used accumulators, which will need a huge amount of electricity to be reclaimed. Therefore, at first, we need a renewable energy/electricity origin!
What are u doing about the electric car?
The problem with electric cars is, where does the electricity come from to charge them up? Most electricity is generated by burning coal or oil. Some is hydroelectric, and some is generated by burning natural gas. If you are burning oil or natural gas to generate electricity for your electric car, you are WASTING half of it; it would be better to carry the oil or natural gas with you, and use it for fuel. The only electricity source that really makes sense for electric cars is something that cannot be made portable, and produces less total pollution that burning gas; nuclear or hydroelectric powerplants. Unfortunately, there isn't nearly enough nuclear or hydro power to waste on electric cars.
Why do the Amish not use electricity?
The Amish have no problem with electricity, but they worry about what electricity can bring to their homes, such as radio, television, and other things that may connect them with the people they consider "outsiders." They want to be as little connected with "outsiders" as possible. However, some Amish bishops allow a few families to have electric lighting.
