Pagina 50 - The force of the current in a galvanic circuit is directly as the sum of all the tensions, and inversely as the entire reduced length of the circuit, bearing in mind that at present by reduced length is understood the sum of all the quotients obtained by dividing the actual lengths corresponding to the •homogeneous parts by the product of the corresponding conductivities and sections.
Pagina 202 - ... resistance of that part of the circuit. Here a new term is introduced, the resistance of a conductor, which is defined to be the ratio of the electromotive force to the strength of the current which it produces. The introduction of this term would have been of no scientific value unless Ohm had shown, as he did experimentally, 'that it corresponds to a real physical quantity ; that is, that it has a definite value which is altered only when the nature of the conductor is altered.
