An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...
This schematic diagram shows the arrangement of NOT gates within a standard 4049 CMOS hex inverting buffer. The inverter is a basic building block in digital electronics. Multiplexers, decoders, state machines, and other sophisticated digital devices may use inverters. The hex inverter is an integrated circuit that contains six inverters.
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

Separable assembly or sub-assembly (e.g. printed circuit assembly) AT: Attenuator or isolator: BR: Bridge rectifier (four diodes in a package) often changed to "D" for diode BT, BAT: Battery or battery holder: often shortened to "B" C: Capacitor: CB: Circuit breaker: CN: Capacitor network: may be simplified to "C" for capacitor D, CR: Diode ...
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
The mutual goal of IEEE Std 91-1984 and IEC 617-12 was to provide a uniform method of describing the complex logic functions of digital circuits with schematic symbols. These functions were more complex than simple AND and OR gates. They could be medium-scale circuits such as a 4-bit counter to a large-scale circuit such as a microprocessor.
There is a (small but extensible) library of symbols available. Creating diagrams using this template is slightly slower than in specialised programs, but it is very flexible and produces nice vector output. A simple symbol library based on well-known package, circuit_macros. The above mentioned points are true with the older versions of Inkscape.
