# Control Systems/Physical Models

## Physical Models

This page will serve as a refresher for various different engineering disciplines on how physical devices are modeled. Models will be displayed in both time-domain and Laplace-domain input/output characteristics. The only information that is going to be displayed here will be the ones that are contributed by knowledgeable contributors.

## Electrical Systems

Circuit Theory
Electronics
Component Time-Domain Laplace Fourier
Resistor R R R
Capacitor ${\displaystyle i=C{\frac {dv}{dt}}}$  ${\displaystyle G(s)={\frac {1}{sC}}}$  ${\displaystyle G(j\omega )={\frac {1}{j\omega C}}}$
Inductor ${\displaystyle v=L{\frac {di}{dt}}}$  ${\displaystyle G(s)=sL}$  ${\displaystyle G(j\omega )=j\omega L}$
