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 ...
The symbol for a battery in a circuit diagram. It originated as a schematic drawing of the earliest type of battery, the voltaic pile . An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [ 1 ] for powering electrical devices.
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.
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.

A simple schematic showing wires, a resistor, and a battery The basic components of analog circuits are wires, resistors, capacitors, inductors, diodes , and transistors . Analog circuits are very commonly represented in schematic diagrams , in which wires are shown as lines, and each component has a unique symbol.
Standard battery nomenclature describes portable dry cell batteries that have physical dimensions and electrical characteristics interchangeable between manufacturers. The long history of disposable dry cells means that many manufacturer-specific and national standards were used to designate sizes, long before international standards were reached.
