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.
Lighting circuits are basically radial circuits. There are two distinct types of lighting, circuit the loop-in circuit and the older junction box circuit. Most houses combine aspects of both types of circuits. The loop-in circuit has a cable, running from light to light terminating at the last light as in the conventional radial circuits and then single cable run from the lights to the light switches. The other type of lighting circuit has a junction box for each light.
