A generator converts mechanical energy into electrical energy, while a motor does the opposite - it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.

How is electricity produced at a power station?
In a coal-fired power station, a boiler burns coal to produce steam. The steam makes a turbine spin. The turbine drives an electricity generator. The electricity from the generator is converted to a higher voltage by a transformer. This higher voltage is to enable transmission over long power lines without losing too much energy. When it comes to reach our homes, it is then converted back into lower voltage by other transformers. Nuclear power stations are similar - instead of a coal-fired boiler, a nuclear reactor creates the steam. Wind turbines use the blades to turn the generator.
Which method of generating electrical energy results in electricity that is relatively easily distributed to where it is needed when it is needed?
using coal-fired power plants
What converts electricity to mechanical power?
In a modern coal fired power plant the mechanical motion of turbines is transferred by a shaft to a generator, where magnets spin within wire coils to produce electricity
What is electricity and what are 3 major ways that it is produced?
Electricity is the flow or potential of electrons , it is produced using 1) hydro electricity (water flows from dam to propel a water wheel connected to an electric motor(alternator) , 2) using burning coal in coal fired stations (uses burning coal to heat water in to steam ,which steam then turns a gas turbine that is connected to an electric generator/alternator 3) using windfarms (uses a giant aerodynamic propeller to turn an alternator(electric motor/generator) from the force of wind.
What are the energy transformations that take place in Hydroelectric Dam Power Plants?
In hydroelectric power moving water turns spins a turbine. A shaft from that turbine sticks into a generator. That produces electricity. In a coal fired power plant coal heats water and steam from the boiling water turns a shaft that sticks into a generator. That makes electric power. Any source of power that can make a large shaft turn can produce electricity. The electricity comes out of the generator on wires. It goes to a power transformer. The transformer turns it into high voltage electricity. That way it can travel over transmission lines without losing energy. It is also called wholesale power. It is like a grocer who buys large boxes of cereal and cuts open the large cardboard boxes and then puts the family size boxes on the shelf to sell. You can not use this high voltage electricity. It is so powerful, it would cook you. It goes to a substation where it goes to another transformer. There is reduced in power to where it is safe to put in wires that run down the streets. Then it goes to another transformer where it becomes safe to put in the wires that go to your home.
In a modern coal fired electric plant the mechanical energy of turbines is tranformed into electrical energy by?
A generator, which is driven by the turbine
what are energy transformations in a coal fired power station?
Coal is burned to produce heat, which then is transferred to water/steam, which produces mechanical power in the steam turbine, which produces electrical power from the generator
What are the energy transformations in a coal fired power station?
Coal is burned to produce heat, which then is transferred to water/steam, which produces mechanical power in the steam turbine, which produces electrical power from the generator
What is a coal-fired energy plant?
A coal-fired energy plant is one that burns coal (as the source of energy) to make electricity or drive machinery.
Which type of power station uses chemical energy to generate electricity coal fired or nuclear?
Coal fired
What is the machine in a power station that changes kinetic energy into electrical energy?
for instance generator, crusher, boiler, coal
How is electricity generated in coal fired power plant?
in your question itself you have said that coal-fired yes electricity is generated by burning coal a large amount of heat is generated as a result. this heat energy is used to heat water inside the boiler tubes. the water is converted to dry saturated steam at this state the temperature is about 540 degree celcius and pressure about 140 kg/sq.cm. this steam is made to expand in a turbine whose shaft is coupled to a generator. when turbine blade rotates due to steam the generator armature also rotates resulting in generation of electricity. simply the heat energy produced by burning coal to heat steam is converted into mechanical energy in steam turbine and then into electrical energy by the generator.....
How does a coal fired power station produce electricity?
A coal fired station burns coal to produce heat. The heat boils water to produce high pressure and temperature steam. The steam expands in a turbine to rotate the shaft. The turbines rotation drives a generator. The generator produces electricity which is sent out to the consumers.
What is the energy conversion that occur when coal is formed and then burned to produce thermal energy?
Conversion from chemical potential energy to thermal energy.
What type of energy is found in a coal fired power station?
chemical energy
What type of energy is in a coal fired power station?
Heat energy i think...
What coal is its main use in the US?
It is burned in coal-fired power plants to supply energy.
