What is Ground in Electronic Circuits In a circuit with one battery (with a positive and a negative terminal), we usually refer to the negative terminal as ground. Let me explain what ground is. Flow of Current When the Ground Symbol is Shown. To see how the current flows in a circuit diagram with ground symbols, just schematics - Use of ground symbols in circuit diagrams In this question is the following diagram for a voltage booster intended for small battery powered devices. The TPS61200 spec says GND is control/logic ground and PGND is power ground but this isn't reflected in the symbols chosen in the diagram. I'm also puzzled why the link to earth is shown on GND rather than on PGND. From this key it seems that various parts of the above circuit are to be Electrical Symbols | Electronic Symbols | Schematic symbols 107 rowsElectrical Symbols & Electronic Symbols.

Circuit symbols are used in circuit schematic diagrams which show how a circuit is connected together electrically. The standard circuit component symbols and circuit symbols are important for circuit schematic diagrams. Electronic Components and Circuit diagram Symbols The Symbols are very important to represent Electronic components in a circuit diagram, without electronic symbol the design of circuit and schematics are very difficult and also knowing the components is very must to read the circuit diagram representation.
