Surprises of the Transformer as a Coupled Oscillator System
Silva, J. P.; Silvestre, A. J.
European Journal of Physics, v29 n3 p413-420 May 2008
We study a system of two RLC oscillators coupled through a variable mutual inductance. The system is interesting because it exhibits some peculiar features of coupled oscillators: (i) there are two natural frequencies; (ii) in general, the resonant frequencies do not coincide with the natural frequencies; (iii) the resonant frequencies of both oscillators differ; (iv) for certain choices of parameters, there is only one resonant frequency, instead of the two expected. (Contains 4 figures and 2 footnotes.)
