Electronics Fundamentals/Passive Components/Capacitor

Capacitor is an Electronic component that can temporarily store an electric charge

Capacitor is an electronic component made from 2 conducting plates seperate by a non conducting dielectric

${\displaystyle C=\epsilon {\frac {A}{l}}}$

${\displaystyle V={\frac {Q}{C}}}$

${\displaystyle Q=CV}$

${\displaystyle C={\frac {Q}{V}}}$

${\displaystyle X={\frac {1}{\omega C}}\angle -90}$

${\displaystyle X={\frac {1}{j\omega C}}}$

${\displaystyle X={\frac {1}{sC}}}$

${\displaystyle Z=X+R}$

${\displaystyle Z=R\angle 0+{\frac {1}{\omega C}}\angle -90={\sqrt {R^{2}+({\frac {1}{\omega C}})^{2}}}\angle {\frac {1}{\omega RC}}}$

${\displaystyle Z=R+{\frac {1}{j\omega C}}={\frac {1}{j\omega T}}}$ Where T = RC

${\displaystyle Z=R+{\frac {1}{sC}}}$

${\displaystyle Tan\theta ={\frac {1}{\omega CR}}={\frac {1}{\omega T}}}$

${\displaystyle {\frac {1}{2\pi fT}}={\frac {1}{2\pi }}{\frac {t}{T}}}$

Most Capacitors are available in Disk or Cylynder
