Gustav Robert Kirchhoff was a German physicist who contributed to the fundamental understanding of electrical circuits, spectroscopy, and the emission of black-body radiation by heated objects. He coined the term black-body radiation in 1862.

Who invented the Kirchhoff's law?

This chapter examines the Kirchhoff's laws, created by the German physicist Gustav Robert Kirchhoff and how these laws can be used to find unknowns in electric circuits. To use the Kirchhoff's laws, it is necessary to understand two concepts: nodes and meshes.

What did Kirchhoff invent?

In 1860 Robert Bunsen and Gustav Kirchhoff discovered two alkali metals, cesium and rubidium, with the aid of the spectroscope they had invented the year before. These discoveries inaugurated a new era in the means used to find new elements.
