SinRLC ​

Series RLC circuit driven by a sinusoidal voltage input.

This component models a series RLC circuit. It consists of a resistor (R), an inductor (L), and a capacitor (C) connected in series with an ideal voltage source. The voltage provided by the source is a sinusoidal waveform generated by a Sine block. A ground component provides the reference potential. Initial conditions for the inductor current (iL(0)) and capacitor voltage (vC(0)) are specified directly in the relations section of the component model.

Usage ​
