An electronic symbol is a pictogram used to represent various electrical and electronic devices

An electronic symbol is a pictogram used to represent various electrical and electronic devices (such as wires, batteries, resistors, and transistors) in a schematic diagram of an electrical or electronic circuit.

Some symbols represent components which ceased to be used routinely as newer technologies were introduced.
