Obal elektronikow:

". In electronic circuit theory, a "ground" is usually idealized as an
infinite source or sink for charge, which can absorb an unlimited amount of
current without changing its potential. Where a real ground connection has a
significant resistance, the approximation of zero potential is no longer
valid. Stray voltages or earth potential rise effects will occur, which may
create noise in signals or if large enough will produce an electric shock
hazard.
The use of the term ground (or earth) is so common in electrical and
electronics applications that circuits in portable electronic devices such
as cell phones and media players as well as circuits in vehicles such as
ships, aircraft, and spacecraft may be spoken of as having a "ground"
connection without any actual connection to the Earth. This is usually a
large conductor attached to one side of the power supply (such as the
"ground plane" on a printed circuit board) which serves as the common return
path for current from many different components in the circuit." From:
