Module 2 : Electrostatics
Lecture 10 : Capacitance
  The potential difference between the plates is
\begin{displaymath}\phi = -\int_2^1 \vec E\cdot\vec{dl} = Ed = \frac{Qd}{A\epsilon_0}\end{displaymath}
  The capacitance $C$is
 
\begin{displaymath}C = \frac{Q}{\phi} = \epsilon_0\frac{A}{d}\end{displaymath}
  Spherical Capacitor :
  The spherical capacitor consists of two concentric spherical conducting shells of radii $R_1$and $R_2$.
