Simple Derivation of Kirchhoff’s Laws and Analogous Laws From Symmetries

Kirchhoff’s laws are undoubtedly the best known laws of electricity. Hence, they have been taught and used widely. So, it may come as a surprise to still write a paper about it. However, for reasons of clarity and wide applicability, it is useful to derive Kirchhoff’s laws with minimal assumptions and using only elementary arguments. This brings some deeper reflections on the role and value of these laws.
