Ohm's Law Quotes (1 quote)
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.
[S = A / L; now written as Ohms Law: V = i R.]
The first expression of Ohm's Law, From Die Galvanische Kette mathematische bearbeitet (1827), 36. As translated by William Francis in The Galvanic Circuit Investigated Mathematically (1891), 50. This is now known as Ohms Law: V = i R, or i = V / R. From the original German, Die Grφsse des Stromes in einer galvanischen Kette ist der Summe aller Spannungen direkt, und der ganzen reduzirten Lδnge der Kette umgekehrt proportional. Ohm uses S for the Strength of the current, A for total potential difference (or voltage) and L for reduced length which is now interpreted directly as resistance of the circuit. The translation footnotes: Reduced length is the length of a copper wire of a given thickness, the resistance of which is equivalent to the sum of the resistance in a circuit, Ohm calls a reduced length." Charles Wheatstone in his Bakerian Lecture (15 Jun 1843).
