Georg Ohm published Die galvanische Kette, mathematisch bearbeitet in Berlin in 1827. This treatise presented his complete theory of electricity, including the mathematical relationship between voltage and current known as Ohm's law. The work synthesized earlier experimental findings on resistance and conduction, establishing a foundational principle in electrical science.

Background and detail
Publication Details. The treatise Die galvanische Kette, mathematisch bearbeitet was published in Berlin in 1827. It contained Ohm's complete theory of electricity, describing measurements of applied voltage and current through simple circuits. The book introduced the constant of proportionality, resistance, to describe the relationship between current and voltage.
Legacy. The relationship described in the book became known as Ohm's law, stating that current is directly proportional to voltage in an ohmic conductor. Ohm's name was later incorporated into electrical terminology, with the ohm adopted as the SI unit of resistance.
