Worksheet: Capacitance of a Cylindrical Capacitor

In this worksheet, we will practice calculating the capacitance produced by concentric charge-storing hollow cylinders of different sizes and separations.


If the capacitance per unit length of a cylindrical capacitor is 20 pF/m, what is the ratio of the radii of the two cylinders?

  • A 1 2
  • B 1 8
  • C 1 1 6
  • D 1 4
  • E 1 1
