Geothermal power plants produce electricity by using steam from hot underground water to turn turbines and activate a generator. Some types of geothermal power plants use the steam to directly turn the turbine, while others use the steam to heat a fluid used to turn a turbine.Know More
The three types of geothermal power plants are binary cycle power plants, dry steam power plants and flash steam power plants.
Flash steam power plants are the most common type of geothermal power plant in the United States. Flash steam power plants use water wells, tapping into underground bodies of boiling water. As the hot water ascends up the well, it produces steam, which is redirected from the water and used to rotate turbines. Excess water and steam are returned to the reservoir in order to ensure sustainability.
Dry steam power plants extract steam directly from extremely hot underground water sources, and they use the energy to turn turbines and generate electricity. In the United States, this form of geothermal power production is only used in a volcanically active area of California.
Binary cycle power plants use slightly cooler water to heat an alternative fluid that has a lower boiling point. This "working fluid" evaporates, and it is used to turn turbines and generate electricity.Learn more about Electricity
The abbreviation "mA" denotes the International System unit for electrical current known as the milliampere. One milliampere is equal to one-thousandth of an ampere. The unit is named for the 18th and 19th century French physicist Andre-Marie Ampere, who studied electromagnetism.Full Answer >
Electricity is important because it is versatile, controlled easily and is used in everyone's daily life. Without electricity, humans would have to use other forms of energy that are less efficient.Full Answer >
To build a generator, create a coil using a nail, two cardboard disks, some insulating tape and a lot of copper wire wound about the nail. Connect the ends of the wire to a light bulb, and attach a magnet to a hand drill. Spinning the drill next to the coil will create electric current and light up the bulb.Full Answer >
A generator works by converting mechanical energy supplied by an engine into electrical energy, using the principles of Faraday's law of magnetic induction. Magnetic induction is caused by moving a magnet near a conductor, such as coils of copper wire. This movement of the magnet creates an electrical current by inducing a voltage difference, which acts as pressure on the electrons and drives them to flow through a circuit.Full Answer >
