Types Of Electrical Circuits There are basicly three types of basic electronic circuits a Series Circuit, Parallel Circuit, and Series Parallel Circuit this is a combination of both series and parallel circuits.

Examples would be lamps, heaters, vacuum cleaners and kitchen items such as kettles, refrigerators etc.
