 During the 1820s, Fechner began his first experimental work, taking as his subject the new and exciting field of electricity. He conducted experiments to test, and to perfect the measurements for, Ohm’s  law,[5]  which had been discovered in 1826, but which was at first very controversial. Fechner’s exact observations and experiments were highly praised and contributed to the general acceptance of Ohm’s law. The experiments were collected under the title Maßbestimmungen über die galvanische Kette (Leipzig: Brockhaus, 1831).
