What are the Ring Circuit and Radial Circuit?

What Is Radial and Ring Circuit?

Think a simple Circle what has radius and periphery. The electrical circuit in your wiring system which is look like radius is called Radial circuit and which one is look like periphery or ring is called Ring circuit. Oh! this definition seems to layman, not professional; lets know detail-  
A radial circuit is an electrical circuit where the feeders to each socket is taken directly from the consumer unit or distribution board (DB) or circuit Breaker (CB) like a 20A MCB. 
A ring circuit is an electrical circuit which has two feeders both come from the same 32A MCB or RBCO in the consumer unit, and head off to different ends of a loop circuit. Ring circuit also known as Ring Main circuit. What Is the Advantages of Ring Circuit? In a ring circuit simply put it, the wiring is connected at both ends of the circuit. The main advantage of ring main circuit is if any single connector is broken or disconnected at any point in the circuit all the other sockets wi…

Working Principle of Smoke Detector

Basic Working Principle of Ionized and Photoelectric Smoke Detectors for Fire Alarm System Smoke Detector is the main sensing device in Fire Alarm System. To understand the basic working principle of smoke detector, we should remember Ionization and Photoelectricstructure, smoke detectors are manufactured basically based on these two principle. According to these rules there are mainly two basic types of Smoke Detector, you will find in the market.

Ionization Smoke DetectorPhotoelectric Smoke Detector
How Ionization Smoke Detector Work

In ionized smoke detector, basically two positive and negative charged plates are consisted in an ionization chamber wherein a radioactive material like americium 241 is placed, shown in figure-1.1.
Air molecules collide with radioactive particles and extricate their electrons. Since the molecules lose electrons, they become positively charged ions; the same as other molecules gain electrons, they become negatively charged ions. Equal numbers of positive and…
