ohm
Noun
Meaning
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.

Also in the 19th century, Wheatstone, Ohm, and Henry developed the analogy between electricity and acoustics.
Again for the case of a hypothetical 1 mA, 500 ohm movement on a 1 ampere range, the shunt resistance would be just over 0.5 ohms.
A common solution to help stabilise the output devices is to include some emitter resistors, typically one ohm or so.
By 1873, the British Association for the Advancement of Science had defined the volt, ohm, and farad.
From this, Ohm determined his law of proportionality and published his results.
It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second.
