from one place to another. Since wire is a good conductor, it has a low resistance to the flow of electricity. The printed circuit (PC) board used in this kit uses traces of copper etched on an insulating fiberglass back plane in place of individual wires. Resistors conduct electrical current, but they are designed to impede the flow of electrons.

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
