Volt equivalent definition

Imagine a very dilute solution of an electrolyte, at a concentration c equiv. per liter, to be placed in a cube of 1 cm. side with square electrodes of 1 sq. cm. area at opposite faces, and suppose an e.m.f. of 1 volt to be applied. By definition, the specific conductance (ic) is the conductance of a centimeter cube, and the equivalent conductance of the given dilute solution, which is virtually that at infinite dilution, is 1000 k/c [see equation (5)], so that... 

The heat transfer was originally measured in units of calories, where one calorie was defined as the quantity of energy required to raise one gram of pure water from 14.5 to 15.5 °C at one atmosphere. This definition has been supplanted by the introduction of the joule, which represents the energy specified by the conversion factor 1 cal = 4.184 joules. One joule is also equivalent to the energy developed in a circuit by an electric current of one ampere flowing through a resistance of one ohm (driven by a potential difference of one volt) in one second. 

Sometimes bonding energies are expressed per atom or per ion. Under these circumstances, the electron volt (eV) is a conveniently small nnit of energy. It is, by definition, the energy imparted to an electron as it falls throngh an electric potential of one volt. The joule equivalent of the electron volt is as follows 1.602 X 10 J = 1 eV.
