The two types of electricity are static and current. Static electricity is the buildup of an imbalanced electrical charge on the surface of objects that causes objects to be attracted to each other. Current electricity is the flow of electrons through a conductor.Continue Reading
Static electricity is discharged when two opposite, imbalanced charges find a path to connect both groups and equalize the charges. This equalizing of charges can produce a spark or shock that can be felt, seen and/or heard.
There are two kinds of current electricity: alternating (AC) and direct (DC). Current electricity can cause the heating of a conductor, such as the coil on an electric stove.Learn more about Electricity
There is no metal that does not conduct electricity entirely, but there are some metals that are less effective conductors than others. Metal atoms have electrons in their outer shells that are not tied to any particular atom and can flow freely within the metal when electricity is applied.Full Answer >
Saltwater is a good conductor of electricity because it is an electrolyte solution. Substances such as salts, acids and hydroxides that also are electrolytes can conduct electric current. Saltwater is a mixture that consists of water and sodium chloride. When sodium chloride dissolves in water, the water separates the sodium and chlorine ions.Full Answer >
Wind turbines turn the kinetic energy of the wind into mechanical energy and then electricity through the use of a shaft and a gearbox that power an internal generator. Sensors in the wind turbine allow it to turn and adjust its angle for optimum wind capture. Electricity from the turbine generator goes to a substation, where it is converted to a high voltage capable of transportation through power lines.Full Answer >
Silver is the best metal conductor, but graphene is the best overall material at conducting electricity. Graphene consists of carbon atoms arranged in extremely thin sheets, and has the lowest electrical resistance of any commonly known material.Full Answer >
