Are all magnetic materials good conductor of electricity?
all conductor of electricity are magnetic substance. if no,state your reason
Can you power a wind turbine with a fan to create infinite power?
What would power the fan? What you describe is a "Perpetual Motion" machine, something that needs no energy, or creates its own energy to operate. The reason such things don't work is because of energy loss, usually due to friction or gravity. The fan loses or wastes electrical energy which is turned to heat by friction in its moving parts and by electrical resistance in internal and external wiring. Some energy is also lost in moving the air. The turbine also loses energy from the wind in its own friction before turning it into electricity. When you add up all those losses, the fan requires more energy than the turbine provides. You can't power a sail boat with an attached fan either, but that's a whole other reason, Newton's 3rd Law of motion.
Can an electric current generate an electromagnetic wave?
Not a constant electric current but a changing one will generate electromagnetic waves.First: If you have a lone electron, and it is accelerated in any way, it will send off an electromagnetic wave. This is because a changing electric field generates a magnetic field.It is also true that changing magnetic field will generate an electric field. This is the reason that if you have an electric current, which is generating a magnetic field, and you change the current you generate an electromagnetic wave. To generate a continuous sinusoidal electromagnetic wave you continuously change the current sinusoidally.
How is electricity wasted in schools?
in schools electricity is wasted by: students don't switch off the lights and fans when going out. this is the main reason for the wastage of electricity as the lights and fans without there being any person in the class. in some schools lights are extra , ie , more than what is required.
What are the Advantages and disadvantages of a Combined Cycle Gas Turbines?
A combined cycle is characteristic of a power producing engine or plant that employs more than one thermodynamic cycle. Heat engines are only able to use a portion of the energy their fuel generates (usually less than 50%). The remaining heat (e.g. hot exhaust fumes) from combustion is generally wasted. Combining two or more "cycles" such as the Brayton cycle and Rankine cycle results in improved overall efficiency. It can also work with the Otto, diesel, and Crower cycles which may allow it to be suited to automotive use. Aside from the Rankine cycle, the Stirling cycle could also be used to re-use waste heat in automotive or aeronautical applications, for the simple reason that there is less weight (water) to carry and that stirling engines or turbines can be made to operate with low temperature differences.In a combined cycle power plant (CCPP), or combined cycle gas turbine (CCGT) plant, a gas turbine generator generates electricity and the waste heat is used to make steam to generate additional electricity via a steam turbine; this last step enhances the efficiency of electricity generation. Most new gas power plants in North America and Europe are of this type. In a thermal power plant, high-temperature heat as input to the power plant, usually from burning of fuel, is converted to electricity as one of the outputs and low-temperature heat as another output. As a rule, in order to achieve high efficiency, the temperature difference between the input and output heat levels should be as high as possible (see Carnot efficiency). This is achieved by combining the Rankine (steam) and Brayton (gas) thermodynamic cycles. Such an arrangement used for marine propulsion is called Combined Gas (turbine) And Steam (turbine) (COGAS).

Is electricity widely used today?
electricity is widely used today because otherwise we wouldn't have computers and TVs. the reason many people believe electricity to be a thing of the past, is because there are so many debates about whether we should be using it and how we should generate electricity. no matter what the source is fore the electricity it is always the same end product.
How can water supply electricity?
Water can supply electricity in usually one reason - the water wheel, or it's close cousins. The water pushes on the wheel, and turns the water wheel. As the wheel spins, it creates mechanical energy. This mechanical energy is fed through a converter, which turns it into useable electricity. It is the same concept as wind with a wind turbine.
What does the Grand Coulee Dam on the Columbia River produces?
Water from the dam makes turbine spin, these turbines spin generators that generate the electricity. The water is pulled down by gravity. The reason to build a dam is to have a large and constant supply of water for this process. This is called Hydroelectric power. Hydro means water.
Can candles and magnets produce electricity?
I can think of two ways to do that:1). Place a burning candle near a photovoltaic (solar) cell. The cell will convertsome of the heat and light energy from the candle flame to electrical energy.2). This one is more complicated and takes more ancillary peripheral stuff.-- Use the burning candle to heat and boil a container of water.-- Guide the steam from the boiling water through the fan of a small turbine generator.
How can you power a light bulb with a carrot?
It is impossible to power a light bulb with a carrot. This is because a carrot contains no electricity.

How do windmills store electricity?
I take it that you are referring to a wind turbine? A wind turbine doesn't save energy; it generates energy. It can be argued that it is more 'eco-friendly', but of course it takes energy to manufacture and install wind turbines, and the only reason they are used is because they are heavily subsidised through increase energy bills to consumers; without these subsidies, wind turbines wouldn't even be considered as a practical source of energy. This is because the energy generated is appallingly-low, and their output cannot be guaranteed to match demand, and they are very expensive.
Where is electricity generated?
Mostly it is generated by generators driven by steam turbines. The steam raising for this purpose can be fuelled by coal or natural gas, or nuclear reactors.The total of these methods is about 89 percent of total electricity generation.There are some large hydro schemes where the generators are driven by water flow, these account for about 7 percent. Wind power is about 0.7 percent, and other methods make up the rest. (figures for USA year 2006)
