ENGLISH MEANING
noun
1.
The
standard
unit
in the
measure
of
electrical
resistance
,
being
the
resistance
of a
circuit
in
which
a
potential
difference
of one
volt
produces
a
current
of one
ampere
. As
defined
by the
International
Electrical
Congress
in
1893
, and by
United
States
Statute
, it is a
resistance
substantially
equal
to
109
units
of
resistance
of the C.G.S.
system
of
electro-magnetic
units
, and is
represented
by the
resistance
offered
to an
unvarying
electric
current
by a
column
of
mercury
at the
temperature
of
melting
ice
14.4521
grams
in
mass
, of a
constant
cross-sectional
area
, and of the
length
of 106.3
centimeters
. As
thus
defined
it is
called
the
international
ohm.
