O problema dos dois capacitores revisitado

Abstract: Discutimos o problema da descarga de um capacitor associado a outro, idêntico e inicialmente descarregado. É sabido que, com ou sem a presença de resistência elétrica no circuito, o estado final de equilbrio, assim como a energia dissipada no processo, são sempre os mesmos. O mecanismo de dissipação no caso em que não há resistência elétrica é a irradiação do sistema e no caso em que a resistência elétrica está presente ocorrem ambos, irradiação e dissipação por efeito Joule, devido à interação dos elétrons de… Show more

“…We have analysed elsewhere [4] the problem of the two capacitors, the discharge of a capacitor associated with an identical and initially discharged, where the equilibrium state as well as the energy dissipated in the process are always the same, regardless the presence of a resistor in the system. We have made clear how this system reaches equilibrium, and…”
