• Resumen

  • In this paper, charging and discharging processes of different cupacitors in electrical RC circuit are considered theoretically and experimentally. The non-local behaviors in these processes, arising from the time fractality, are investigated via fractional calculus. In this context, the time fracitonal differential equation related to electrical RC circuit is proposed by making use of Caputo fractinal derivative. The resulting solution exhibits a feature in between power law and exponential law froms, and is obtained in terms of Mittaf-Leffler function which describes physical systems with memory. The order of fractional derivative characterizes the fractality of time and being considered in the interval 0 < "inf" <= 1. The traditional conclusions are recovered for "inf"=1, where time becomes homogenous and system has Markovian nature. By using time fractional approach, thediscrepancies between the experimentally measured data and the theoretical calculations have been removed.
