Electronics Fundamentals/Passive Components/Capacitor

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

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

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

Q=CV

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

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

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

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

Z=X+R

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

Z=R+{\frac {1}{j\omega C}}={\frac {1}{j\omega T}}

Where T = RC

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

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

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

Most Capacitors are available in Disk or Cylynder
