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.
1. A closed path through which an electric current flows or may flow. â¦ Circuits in which a power source is connected to two or more components (such as light bulbs), one after the other, are called series circuits.If the circuit is broken, none of the components receives a current.
