The Galvanic Circuit Investigated Mathematically

Georg Simon Ohm, a German physicist, mathematically investigated the galvanic circuit, establishing a fundamental relationship between electrical current, voltage, and resistance. His work, published in The Galvanic Circuit Investigated Mathematically (1827), led to what is now known as Ohm's law.1

This law states that the current flowing through a conductor is directly proportional to the potential difference (voltage) across it and inversely proportional to its resistance. Mathematically, this is expressed as (V = IR), where (V) is voltage, (I) is current, and (R) is resistance. The unit of electrical resistance, the ohm, is named in his honor. Despite its significance, Ohm's work was initially poorly received.231
