(c) If the dielectric doesn't completely fill the space between the plates, what could you conclude about the voltage across the plates? The voltage across an air-filled parallel-plate capacitor is measured to be 189.0 V. When a dielectric is inserted and completely fills the space between the plates as in the figure below, the voltage drops to 90.0 V. a Co AV AV (a) What is the dielectric constant of the inserted material? (b) Can you identify the dielectric? O O O O nylon paper bakelite neoprene rubber teflon Dielectric
