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.Know More
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
Electrical energy comes from renewable and nonrenewable sources; it is generally inexpensive and readily available, but it leaves many appliances and heating units defunct when power supplies are interrupted. The benefits and drawbacks of electrical energy depend primarily on its source. Electricity created from fossil fuels is generally less expensive for consumers than electricity derived from renewable energy sources, such as solar and wind, but centralized forms of power can leave households and business offices disabled during severe weather.Full Answer >
Electricity, the flow of electric charge, powers much of the technology used in modern society. The Energy Information Administration explains that electricity is a secondary source of energy, meaning that it comes from the conversion of other energy sources.Full Answer >
According to the Occupational Safety & Health Administration, electricity is dangerous because it can cause burns, nerve damage, cardiac arrest and death. Alliant Engery also notes that the majority of the human body is composed of water, which makes it a good conductor of electricity.Full Answer >
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 >
