August 18, 2010 University Physics, Chapter 24 46 Capacitors with Dielectrics (1) ! So far, we have discussed capacitors with air or vacuum between the plates. ! However, most real-life capacitors have an insulating material, called a dielectric , between the two plates. ! The dielectric serves several purposes: Provides a convenient way to maintain mechanical separation between
