Electrical energy describes the energy that charged particles store inside an electric field. There are many different forms of energy and people use multiple forms each day.
An electrical field is the space that surrounds a charged particle. This space helps the particle to work by applying force to it. Potential energy is a system or body's electrical energy relative to how particles arranged around a system or relative to the position of the body. For example, a boulder on a tall hill has a high level of energy due to the potential for it to roll down.Learn More
Most electrical energy is created using electromechanical generators. These devices convert rotational energy to electrical energy by inducing a magnetic field over copper wires. The energy to turn the generators may come from wind or water, or the turbines may be driven by steam heat from nuclear or fossil fuels.Full Answer >
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 >
Surrounding air superheats to more than 18,000 degrees Fahrenheit, expands outward rapidly and produces the strong soundwaves known as thunder when the electrical energy of lightning is discharged in Earth's atmosphere. Most of the energy of lightning is in the form of heat that quickly dissipates in cooler air. Before lightning strikes, the insulating capacity of air breaks down, and the negatively charged atmosphere produces powerful bolts.Full Answer >
Capacitors store energy in an electric field and can come in numerous sizes and types. The basic form set up of a capacitor does not vary from type to type, meaning that all capacitors have two conductors and a dielectric. The dielectric is a type of insulator that separates the two conductors.Full Answer >
