Wind energy is a form of renewable energy produced through machines that use wind as their power source. Wind energy is only possible because of the sun.Know More
The sun heats the atmosphere, but it doesn't do it evenly. This process, along with the rotation of the earth, causes winds that scatter across the varied surface of the earth. That wind can be harvested by wind turbines. The wind turns the turbines, which generates electricity.
The turbines are connected to shafts. When the turbines turn, the shaft turns. The shaft then turns a generator. The turning of the generator creates a flow of electrons, which is electricity. Wind turbines automatically shift to harness the most wind power, based on which direction the wind is blowing.
Two basic types of wind turbines exist. Some spin vertically, like the giant turbines on wind farms that look like pinwheels. Other turbines spin horizontally; these types can be used on the tops of buildings to generate energy.
Turbines on wind farms can produce up to several megawatts of energy, though some produce less. They are grouped together to produce power on a grid. Blades on a large vertical turbine can be as long as 100 yards. Smaller turbines produce less than 100 kilowatts of energy. These types are used in residential areas for homes, and they are usually employed by themselves, though sometimes they work in conjunction with power from the city.Learn more about Electricity
Ohio Electric Motors indicates that the main difference between AC and DC motors is the power source. AC motors are powered by an alternating current while DC motors use a direct current as a power source.Full Answer >
A simple electrical circuit contains four parts: a power source, a load, connectors and a switch. The power source provides energy for the electricity to travel along the circuits and the load is the device that the circuit is designed to power.Full Answer >
The purpose of a diode is to block current from flowing in one direction Diodes are typically used to protect a circuit if the power source is connected in the wrong direction.Full Answer >
A light bulb circuit works when the electric current flowing through the light bulb combines with the current flowing in the battery or power source. The filament and wires in the light bulb conduct electricity so that electric current can move through an electric circuit.Full Answer >
