About Georg Simon Ohm

Georg Simon Ohm was born on March 16, 1789, in Erlangen, Bavaria, Germany, and died on July 6, 1854, in Munich, Germany. Known for his significant contributions to the field of electrical circuits, he is considered a pioneering figure in the discipline of electrical physics.

Ohm came from a relatively poor family and was largely self-educated, motivated by a love of mathematics and experimental physics. He was initially a private tutor, then became a teacher at the Polytechnic School of Nuremberg and later a professor at the University of Munich.

His work was driven by a curiosity to understand the nature of electric current and its behavior in conductive materials, and it was this exploration that led to his formulation of the foundational law of electrical circuits, known as Ohm's law.

Ohm's Discoveries

Georg Simon Ohm is most recognized for his formulation of "Ohm's Law," a fundamental principle that underpins the study of electrical circuits. This law states that the current passing through a conductor between two points is directly proportional to the voltage across the two points.

His work in this area was initially met with resistance and was not well received by his contemporaries. His research on electric circuits was a pioneering effort, and the physics community of his time was slow to recognize its importance. However, Ohm persevered, and his work eventually gained the recognition it deserved.

Ohm's Key Achievements

Ohm's greatest achievement was his formulation of Ohm's Law, a central principle in electrical physics. This discovery significantly influenced the study and understanding of electricity, particularly electrical resistance, and helped lay the groundwork for electrical engineering.

The unit of electrical resistance in the International System of Units (SI) is named the "ohm" in his honor, reflecting the profound impact of his contributions to the field.

Ohm's Formulas

Ohm is famous for formulating Ohm's Law, a fundamental equation in the study of electrical circuits:

Statement of Ohm's Law:

V = I × R


  1. V: Voltage across the two points in the circuit (in volts)
  2. I: Current passing through the conductor (in amperes)
  3. R: Resistance of the conductor (in ohms)
