      James Maxwell's interpretation of Ohm's law states that the electromotive force of a conductor in a certain state is proportional to the current produced. Therefore, the ratio of electromotive force to current, i.e. resistance, does not change with current. Here, the electromotive force is the voltage across the conductor. With reference to the context of this quote, the modifier "in a state" is interpreted as being in a normal temperature state, since the resistivity of a substance is generally temperature dependent. According to Joule's law, the Joule heating of a conductor is related to the current, and the temperature of the conductor changes when the current is conducted through the conductor. The dependence of resistance on temperature makes it difficult to directly check this form of Ohm's law in a typical experiment where resistance depends on current.

     Ohm's first phase of experiments to investigate the decay of the electromagnetic force produced by the current in relation to the length of the wire, the results of which were published in his first scientific paper in May 1825. In this experiment, he encountered difficulties in measuring the strength of the current. Inspired by the galvanometer invented by German scientist Schweiger, he combined Oersted's discovery of the magnetic effect of current with the Coulomb torsion balance method to design a current torsion balance, which was used to measure the current intensity. Ohm emerges from preliminary experiments that the electromagnetic force of an electric current is related to the length of the conductor. There is no apparent direct connection between its relation and today's expression of Ohm's Law. Ohm also did not connect the three quantities of potential difference (or electromotive force), current strength and resistance at that time.
