Circuit diagrams

Circuit diagrams are one method of describing electronic equipment. They are made up of BS3939 standard circuit symbols. READING a circuit diagram is the ability to look at the diagram and understand how the circuitry works. Be aware that the layout of the circuit diagram may be nothing like the physical layout of the actual equipment. Although the circuit diagram shows all capacitors the same size and shape, in reality they will be of assorted sizes, shapes and color. This applies to other components.
