Classical Physics


From Kirchhoff to Faraday

Authors: Christopher Rodgers

Kirchhoff’s law of voltages is a standard in the education of students learning circuits for the first time. Even when this is done in physics classes, there is no attention paid to the origins of this law. This is a disservice to the students, because this robs them of an opportunity to see a real world application of conservation laws that they don’t need to take on faith. Furthermore, if we introduce a magnetic field to the systems, things get more interesting. This allows the student to see a firsthand application and emergence of a fundamental property of the universe and its effects on everyday things, Faraday’s law. In this work we will be exploring these two phenomena from first principles, and showing how Kirchhoff is a limiting case of Faraday’s Law.
