- 0.2390 calories - Unit of energy - A unit of work which is equal to 107 units of work in the C.
G. S. system of units (ergs), and is practically equivalent to the
energy expended in one second by an electric current of one ampere in a
resistance of one ohm. One joule is approximately equal to 0.738 foot
pounds.
- German physicist in a message unfinished mobile - Measure of resistance - Old heads met a little resistance - Resistance unit - Unit of electrical resistance - Unit of resistance - 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.
