RLCModel ​

An electrical circuit model featuring an inductor in series with a parallel resistor-capacitor combination, driven by a constant voltage source.

This model represents an electrical circuit where an inductor (L) is connected in series with a parallel arrangement of a resistor (R) and a capacitor (C). This L-(R||C) configuration is subjected to a constant voltage provided by a voltage source. The key dynamics are governed by Kirchhoff's laws. Initial conditions are specified for iL(0)=0A and vC(0)=10V. The system is expected to reach a steady state where vC=Vsig=30V.
