Electricity powers a wide range of devices that cannot work with other forms of energy, but it can be dangerous. Without electricity, modern computer technology would not work. Generating electricity, however, can cause significant environmental harm.Continue Reading
Electricity provides a means of transferring energy over large distances, and electrical infrastructure ensures that the entire population of developed nations has access to it. Electricity is a powerful source of energy, and it can be used for mechanical tasks. What truly separates electricity from other forms of energy is its versatility. From powering computer monitors to light bulbs, electricity can perform a range of tasks other forms of energy cannot.
However, electricity is potentially dangerous, and small mistakes often lead to electrocutions. Electricians receive years of training before they are able to work, but their training does not prevent all injuries. Wall outlets are potentially dangerous, and water on electrical devices can cause electrocution as well.
Electricity is mostly generated in power plants, and most of these plants release carbon dioxide in the process. This release is one of the major factors for global climate change. There are other technologies that do not pose the same risks, but developing nations cannot afford their high costs. Particulate pollution has a number of significant health effects as well.Learn more about Electricity
Water turbines produce electricity from kinetic energy by using the force of falling water to stimulate an electric generator. There are two types of water turbines: impulse turbines and reaction turbines. According to the U.S. Geological Survey, water turbines are an effective method for supplying short bursts of energy during peak hours of power demand.Full Answer >
According to National Geographic, electricity comes from energy sources such as fossil fuels, wind energy and hydroelectric power. Electricity is transported from a power station via power lines that carry electrical current into communities.Full Answer >
A power transformer is a device that consists of a coil wrapped around an electromagnet that transfers electricity from one circuit to another without changing the frequency of the electric energy. Although the frequency of the electrical energy isn't changed, the voltage and current commonly change when passing through.Full Answer >
The main sources of electricity are fossil fuels, nuclear power and renewable energy. Electricity is a secondary source of energy derived from primary sources.Full Answer >
