Summary: | When a circular loop composed by a RLC circuit begins to oscillate, the oscillation will eventually vanish as an exponentially decaying current, even considering superconducting wires, due to the emission of electric and magnetic dipole radiations. In this work we propose a modification of the Kirchhoff’s voltage law by adding the radiative contributions to the energy loss as effective resistances, whose values are relatively small when compared to typical resistance values, but are fundamental to describe real circuits correctly. We also analyse the change in the pattern of the radiation spectra emitted by the circuit as we vary the effective and electric resistances.
