• A Cylindrical Capacitor :

• As a Gaussian surface, we choose a cylinder of length L and radius r, closed by end caps and placed as is shown.
• It is coaxial with the cylinders and encloses the central cylinder and thus also the charge q on that cylinder.

• From the relation C= q/V, we then have
