  When a circular loop composed by a RLC is put to oscillate, the oscillation
will eventually vanish in an exponentially decaying current, even considering
superconducting wires, due to the emission of electric and magnetic dipole
radiation. In this work we propose a modification on the Kirchhoff voltage law
by adding the radiative contributions to the energy loss as an effective
resistance, whose value is relatively small when compared to typical resistance
value, but fundamental to describe correctly real circuits. We have also
analysed the change in the pattern of the radiation spectra emitted by the
circuit as we vary both the effective and electrical resistance.
