Summary

The direct current is characterised by an unidirectional flow of electrical charges. This means that the charges are always circulating in the same direction. This is the case in nearly all electronic circuits powered by batteries and also for some specific installations (trains). The material that functions in direct circuits is usually marked with the abbreviation "DC".

The alternative current is characterised by an alternate flow of electrical charges. This means that the charges always come and go. This is the case in domestic circuits (houses, etc). The material that uses an alternative current is usually marked with the abbreviation "AC".
