10 ENERGY STORED IN A CHARGED CAPACITOR This bank of capacitors stores electrical energy for use in the particle accelerator at FermiLab, located outside Chicago.

11 CAPACITORS WITH DIELECTRICS

12

13 Types of Capacitors

14 AN ATOMIC DESCRIPTION OF DIELECTRICS (a)Polar molecules are randomly oriented in the absence of an external electric field. (b) (b) When an external field is applied, the molecules partially align with the field.

15 AN ATOMIC DESCRIPTION OF DIELECTRICS

16 Effect of a Metallic Slab A parallel-plate capacitor has a plate separation d and plate area A. An uncharged metallic slab of thickness a is inserted midway between the plates. Find the capacitance of the device.
