SYMBOLIC REPRESENTATION In different field of life we use to represent different items, action or events with a simple diagram, this pictorial representation is known as ‘Symbol’. In different field of life we use to represent different items, action or events with a simple diagram, this pictorial representation is known as ‘Symbol’. So, symbol means pictorial representation of a thing. So, symbol means pictorial representation of a thing.

BENEFITS OF SYMBOLIC REPRESENTATION The pictorial representations can be understand easily. The pictorial representations can be understand easily. The symbols can be understood and learned by even illiterates or uneducated. The symbols can be understood and learned by even illiterates or uneducated. In multi-linguistic world the pictorial representations develops a universal language. In multi-linguistic world the pictorial representations develops a universal language. The pictorial representations emphasis on important aspect of thing. The pictorial representations emphasis on important aspect of thing.

COMMON ELECTRICAL SYMBOLS In electrical science study several symbolic diagrams are used for learning. We will learn some basic and common symbolic diagrams used in study of electricity. In electrical science study several symbolic diagrams are used for learning. We will learn some basic and common symbolic diagrams used in study of electricity. SYMBOLIC DIAGRAM OF WIRE:- The wire is most common thing used in electricity.The wire, made of conducting material, provides path for flow of electric current. SYMBOLIC DIAGRAM OF WIRE:- The wire is most common thing used in electricity.The wire, made of conducting material, provides path for flow of electric current.

1.Symbolic diagram of wire I. Wire joints:- To expand the path of electricity a network of wire is required, hence the wire are inter- connected for larger length. II. Overlapping of wire:- The overlapping of wire means that the wires are crossing each other but wires are not connected

2.Cell and battery and D.C. supply Cell:- The cells are source of electrical energy and represented with symbol showing its two terminal. Cell:- The cells are source of electrical energy and represented with symbol showing its two terminal. Battery:- The combination of two or more cells is known as a battery. Battery:- The combination of two or more cells is known as a battery. Direct current supply:- The electricity in which the current flows in one direction. Direct current supply:- The electricity in which the current flows in one direction.

3.A.C. supply and switch Alternating current supply:- In A.C. electricity, the direction of current and value of voltage keeps changing. It is represented by the symbol of ‘wave’. Alternating current supply:- In A.C. electricity, the direction of current and value of voltage keeps changing. It is represented by the symbol of ‘wave’. Switch:- The switch is a device which is used to make or break the electrical circuit. There are different types of switches used in electrical circuit. Switch:- The switch is a device which is used to make or break the electrical circuit. There are different types of switches used in electrical circuit.

4.Incandescent lamp/bulb, tube light and fan Incandescent lamp/bulb:- The electricity device which is used to give light. Incandescent lamp/bulb:- The electricity device which is used to give light. Tube light:- The tube light is an electrical device, which is used to produce light with help of two other devices, named as:- Tube light:- The tube light is an electrical device, which is used to produce light with help of two other devices, named as:- 1. Starter. 1. Starter. 2. Chock/ballast. 2. Chock/ballast. Fan:- The electric fan converts electrical energy into mechanical energy. Fan:- The electric fan converts electrical energy into mechanical energy.

5.Motor and socket or wall outlet Motor:- The motor is an electrical device which converts electrical energy into mechanical energy. Motor:- The motor is an electrical device which converts electrical energy into mechanical energy. Socket or wall outlet:- The socket are open electrical points which can be used to connect removable electrical appliances. Socket or wall outlet:- The socket are open electrical points which can be used to connect removable electrical appliances. There are two types of sockets:- There are two types of sockets:- 1. Two pin socket. 1. Two pin socket. 2. Three pin socket. 2. Three pin socket.

6.Electrical terminals (in A.C.) and fuse Electrical terminals (in A.C.):-There are three terminals in normal house wiring or electrical system, which are known as:- Electrical terminals (in A.C.):-There are three terminals in normal house wiring or electrical system, which are known as:- 1. Phase- Represented with ‘P’. 1. Phase- Represented with ‘P’. 2. Neutral- Represented with ‘N’. 2. Neutral- Represented with ‘N’. 3. Earth- The terminal of earth is used for safety purpose. 3. Earth- The terminal of earth is used for safety purpose. Fuse:- The fuse is a safety device, which breaks the electric circuit when current flows more than the specified limit. Fuse:- The fuse is a safety device, which breaks the electric circuit when current flows more than the specified limit.
