Capacitance

Written by Jerry Ratzlaff on . Posted in Electromagnetism

Capacitance, abbreviated as C or CAP, is the ability to hold an electric charge.

 

Capacitance Formulas

\(\large{  C = \frac{  Q }{ V }  }\)   
\(\large{  C = \frac{ \epsilon \; A }{ d }  }\)   

Where:

\(\large{ C }\) = capacitance

\(\large{ A }\) = active area of the plate

\(\large{ Q }\) = electrical charge that is stored on the capacitor

\(\large{ \epsilon }\) = permittivity of the dielectric medium

\(\large{ d }\) = perpendicular distance between conductors

\(\large{ V }\) = potential difference (the voltage between the capacitor's plates)

Solve for:

\(\large{ Q = C \; V  }\)

\(\large{ V = \frac{ Q }{ C }  }\)
