This Symbol of switch selects between two connections. It is the symbol of a switch that disconnects current when open. This Symbol shows that wires are not connected on crossing. This Symbol represents the wire connected crossing. It is the symbol that is used to represent a wire. Below is a list of the most commonly used electrical symbols. So to overcome this problem we use electronic symbols because they are easy to draw and this makes circuit easily.
Common Electrical and Electronics SymbolsĪs we are drawings any circuit diagram so we can’t draw the actual components or the part that we need to make a circuit. You can use an online circuit builder to design and test simple circuits at visit the interactive learning guide, download circuit construction kit (parts 1 and 2) or try and make your own circuits from electrical components.2. This circuit diagram below represents the components in the above circuit. the battery acts as the power supply to provide the energy to operate the circuit the conducting leads allow the electric current to flow from the battery the switch can complete the circuit when closed or break the circuit when open the light globe is the load where the electrical energy is converted into other forms, e.g. This simple circuit shown below contains the common components of any electric circuit, i.e. Attached in parallel in circuit.Įlectrical contacts to allow the connection of another device between them Attached in series in circuit.Ī voltmeter used to record the voltage drop between two points, (the change in energy for each coulomb of charge). the circuit is switched ON.Ĭonductor wire - made of metal and used to attach components togetherĪ fixed resistor - a device which offers a particular electrical resistanceĪn ammeter used to record the size of the electric current flowing in wires. the circuit is switched OFF.Ī closed switch, i.e.
It means that using standard symbols can describe to anyone familiar with electrical circuits either how an existing circuit has been constructed or can act as a blueprint for telling someone how a circuit should be built.Įlectrochemical cell - Long, thin side is POSITIVE terminal, shorter, thicker side is NEGATIVE terminalīattery - A number of electrochemical cells attached togetherĪn open switch, i.e. This makes it simpler to show how the various components of a circuit are wired together. Have you wondered what the symbols on the diagrams mean? Scientists and engineers have developed a set of symbols to represent the components of an electric circuit. Have you ever seen an electrical circuit diagram? These diagrams sometimes come with new appliances or may be glued to the inside of appliances to inform electrical repairers.
