More Electrical Information
 

An electric current is simply a flow of electrons. It is measured in amperes. Electric currents include examples such as metallic conduction, where electrons flow through a conductor (i.e. metal wire), and electrolysis, where ions (which is charged atoms) flow through liquid. The charged particles themselves often move very slowly, but the electric force that drives them travels at close to the speed of light.

Electricity is responsible for several physical phenomena, including lightning, electric currents, and electric fields and used in industrial applications such as household electronics and electrical power.

Because the people who install wiring and those who repair it are often not the same person, there are standards for how to install wiring. The standards for electrical wiring are rather basic and easy to understand for homes, as the structure of homes is rarely modified and there are generally low power requirements. Meanwhile, in commercial buildings and offices, it is likely that the wiring is changed more often and there might be special factors that influence the wiring, such as moisture in the walls, etc. In these cases, it is extremely important that electricians are careful to follow standard practice and label the wiring appropriately.
