Circuit Symbols of Electronic Components

Also see: Circuit Diagrams Circuit symbols are used in circuit diagrams which show how a circuit is connected together. The actual layout of the components is usually quite different from the circuit diagram. To build a circuit you need a different diagram showing the layout of the parts on stripboard or printed circuit board. Wires and connections
