Important Electronic Symbols Used In Valve Circuits

Important Electronic Symbols Used In Electronic Circuits

Like you have to understand how to read a road map to visit a place, far away from your home town, the same goes for building electronic circuits. The pictures below show typical examples of how to identify components and important parts of a circuit. Components marked with a plus + sign must always be connected correctly, as shown in the diagrams. In the case of electrolytic capacitors, Wrong polarity will result in the capacitor exploding and making a mess all around. It is important to remember that valves are far more robust in the short terms, compared to transistors but also the Wrong polarity of a rectifier diode will result in similar circumstances, possibly causing more damage. I would advise you to read these pictures very carefully before proceeding with any electronic circuit.
