The Plates of a Parallel Plate Capacitor Each Have an Area

question 49

Multiple Choice

The plates of a parallel plate capacitor each have an area of 0.40 m² and are separated by a distance of 0.02 m. They are charged until the potential difference between the plates is 3000 V. The charged capacitor is then isolated.
-Suppose that a dielectric sheet is inserted to completely fill the space between the plates and the potential difference between the plates drops to 1000 V. Determine the dielectric constant.

• A)0.333
• B)0.666
• C)3.0
• D)6.0
• E)2000
